Fujitsu today announced that it has developed an iris authentication system and has built it into a prototype smartphone. Just by looking at the smartphone’s screen, the user’s iris gets read instantaneously, enabling the smartphone to be unlocked.
Currently, smartphones typically use either a password or fingerprint scan to unlock the screen or for other authentication purposes. Fujitsu’s new authentication method uses iris recognition, which is hard to forge and convenient to use. The screen can be unlocked simply by looking at it, which eliminates the trouble of having to use one’s hands such as at times when one is wearing gloves and cannot use one’s fingerprint. This results in a dramatic improvement in usability. In addition to unlocking smartphones, iris authentication could be used to log into web services without having to input an ID or password, enabling simple and secure access. Fujitsu will explore applying this technology to a wide range of fields, including security systems.
This prototype will be exhibited and demonstrated at Mobile World Congress 2015, running from March 2 through March 5 in Barcelona, at the Fujitsu booth in Hall 5, 5A40.
Smartphones and tablets carry not only personally significant photos and videos, they also are where people access electronic money and personal information, and the importance of security for both personal and business is rising. In light of this, Fujitsu has focused on developing a number of authentication technologies for smartphones, tablets, and computers, including vein authentication for personal computers and fingerprint authentication for mobile phones. While smartphones all come with some form of security as a standard feature today, many users choose not to use these features because of the trouble of inputting a password or using one’s hands. To resolve this problem, Fujitsu developed
the new iris authentication system, which, in addition to being secure, offers ease of use.
About the Technology
1. A new form of biometric authentication using the iris
Iris authentication is one type of biometric authentication. It authenticates a person by authenticating the pattern of the person’s iris, which is the ring around the pupil of the eye. Fujitsu has succeeded in miniaturizing and optimizing existing iris authentication technology for incorporation into a smartphone. The pattern of one’s iris does not change much at all after the age of two, it is difficult to injure its surface, and is difficult to forge.
2. Using infrared light to acquire the iris pattern, and for registration and verification
Movements of the smooth muscle of the iris make human eye openings larger or smaller, adjusting the amount of light that enters the retina. Iris authentication technology discerns a person’s identity using the pattern of the person’s irises, which are unique for each individual, much like a fingerprint. That pattern is read by shining an infrared LED light (*1) on the eyes and taking an image of them with an infrared camera (*2) to acquire the iris pattern, which is registered and used to verify matches. The iris authentication system that Fujitsu has developed achieves highly precise authentication and is able to be used in smart devices for greater convenience.
Fujitsu’s Iris Authentication System
The parts that make up existing iris authentication systems have not had the size or performance that would lend them to use in smartphones. Fujitsu developed a custom compact and high-output infrared LED, and a custom infrared camera. These were combined with camera controller technology and biometric-authentication technology that Fujitsu has been developing for many years. The result is a system that can reliably authenticate the detailed patterns of the iris and that can be used in most everyday situations. Because this uses ActiveIRIS® from Delta ID, a high-speed, high-reliability iris recognition engine, this system can be used at a normal smartphone viewing distance, rather than within the 10-cm range that most existing iris recognition systems require. In standard photobiological safety testing (IEC 62471), the infrared LED light was verified to be safe for the eyes.
The iris authentication system used in the prototype could be used in smartphones and tablets, of course, but could also be used in a wide range of other applications, including security solutions. Fujitsu is conducting ongoing research and development on this iris authentication technology and ways to broaden its scope, with the goal of a commercial implementation during fiscal 2015.
Glossary and Notes
1. Infrared LED
An LED that emits light in a waveband appropriate for capturing an image of the iris.
2. Infrared camera
Unlike normal photographic cameras, this is a special kind of camera that captures the waveband of light emitted by an infrared LED.

It seems that phone manufacturers are running away from their responsibilities Over the last two years, Strand Consult has analyzed and documented the conditions and the challenges that mobile operators face when it comes to creating good mobile coverage across a range of countries. In the report "How mobile operators can reduce the cost for mobile masts and improve mast regulation" we document these challenges and how they can be addressed.
In most countries, telecom regulators, politicians, the media and consumers believe that good mobile coverage is simply a function of the network and is the sole responsibility of the mobile operator. However our research shows that good mobile coverage depends on six factors:
In the report "How mobile operators can reduce the cost for mobile masts and improve mast regulation", we have described the entire process - from the time an operator gets a mobile license to when the customer gets a signal on his phone. We have described the requirements for good mobile coverage and what the political and regulatory system can do to ensure it.
To date, the one factor that has been least understood or discussed is the quality of the phone in relation to mobile coverage. To put it another way, just as there will be differences in how far a car can run on liter of petrol, a phone will vary in performance within a given network.
Strand Consult has access to measurements from operators around the world which demonstrate a big difference in the quality of the phones. Operators have not been able to share this information with consumers because of various rules and gag-orders from handset manufacturers.
At last, together with our report "How mobile operators can reduce the cost for mobile masts and improve mast regulation", we can reveal the world's first independent measurement that shows how nine of the best-selling phones perform on the mobile network standards GSM 900, GSM 1800, UMTS 900 and UMTS 2100.
Professor Gert Frølund Pedersen of Aalborg University together with his research team are some of the world’s leading experts on mobile phone performance and have studied this issue for years. Their recent study focused on how nine of the most popular phones perform when it comes to coverage. They have made painstaking efforts to measure the quality of the phones and published their findings. To ensure fairness and uniformity, the measurements were conducted in a state of the art laboratory with the phones, networking equipment, and head and hand mannequins of users. The results demonstrate definitively that the quality of phone plays a major role in the user’s experience of the network. Read more about the study.
At Strand Consult believe that the debate about mobile coverage also needs to incorporate the role of the mobile phone and that handset manufacturers have a responsibility to make phones that are optimized to the network so that consumers get a good experience with mobile coverage.
Key findings from the study
1. Phone quality varies by 10 fold. From the worst to best phone, there is factor of 10 factor difference in how well the individual phone compete. The antennas inside the best phones are up to ten times better than in the worst phones.
2. It’s in the way that you use it. The way the customer holds on the phone can have an impact on coverage. Sometimes a person holds a phone in such a way that it blocks the interior antenna’s connection to the network. Thus a person can unwittingly aggravate his coverage experience by a factor of 10 just by holding the phone in the wrong way. Users need to learn how to the hold the phone correctly and remember to do it each time they make a call.
3. Phone design can be optimized for humans. Although there are differences in how people hold their phones, a major study shows that about 90% of users hold the phone in one of two ways. (See “A Grip Study for Talk and Data Modes in Mobile Phones.” Pelosi, Mauro; Franek, Ondrej; Knudsen, Michael; Christensen, Morten; Pedersen, Gert Frølund. in: IEEE Transactions on Antennas and Propagation, Vol 57, No. 4, 2009, pp. 856-865) It is possible to design the phone so that the best antenna performance is achieved, for example by using tuning devices.
4. Older versions perform better. The newest and most popular phones, Samsung Galaxy SIII and iPhone 5, fare worse than their predecessors, the Samsung Galaxy SII and the iPhone 4 and 4S when using the lower frequency band, GSM 900 and UMTS 900
5. Hold the phone so that the antenna can connect with the network. The iPhone 4S performs well provided that it is held correctly. The iPhone is designed such that the spacing of the fingers optimizes the antenna signal from the phone. In practice, there is design feature on the frame of the iPhone, and the fingers need to cradle this point. Without this adjustment, the iPhone is one of the worst performing phones.
6. Oldies but goodies. New phones do significantly worse than old phones. Buying a new and popular phone increases the likelihood of getting bad network experience.
7. Standards matter. Phones and networks operate on shared standards, for example GSM 900, GSM 1800, UMTS 900 and UMTS 2100. Choosing a phone that has the preferable standard to the network is extremely important if you want to ensure good coverage.
What should we expect of handset manufacturers
The point of this study and report is not to discredit any phone or manufacturer, but rather to encourage handset makers to put more emphasis on building phones that work better with the network.
We should ask phone makers why the old versions perform better than the new. Given the explosion of phones on the world market, some national or global standards for information of the quality of phones should be made available so that consumers can make more informed decisions. It is important to remember that these measurements reflect only part of the phone’s quality vis-à-vis the network.
Though not measured in this study, it has been documented that phones pose other challenges to the quality of mobile coverage from their hardware, software, as well as the number of apps installed on the phone.
The modern smartphone is very complex and may be responsible for up to 70% of the bad coverage that a user experiences. There is fierce competition among handset manufacturers in the phone market today.
In practice this means that the phones come to market with unfinished product development. Phone manufacturers only correct the errors through software updates once the customer has purchased the phone.
This allows phone manufacturers to lessen their development costs by putting the onus of product quality on operators and consumers. A good example is the iPhone 5 which was launched with a chipset that supposedly supports LTE "4G". However, as millions of customers in various countries have experienced, the iOS software that support LTE is not yet available.
Thus ensuring that phones are optimized for the network takes a backseat to getting the phones to market. We believe that the lack of focus on quality means that phone manufacturers do not do enough to solve these challenges. We believe that transparency in this area may eliminate some of the challenges that customers are experiencing on a daily basis.
The ordinary consumer has no chance to investigate these things on his own. Further,handset producers prohibit operators from publishing the measurements they have. Strand Consult believes that consumers should have such information so that they can make more informed decisions. We support mobile coverage disclosures on phones to help customers determine which phones are right for them. That there is a need for transparency and discussion about the role of the mobile handset in coverage quality. • 1/13
This study was performed in Denmark in autumn 2012. The four Danish network operators (TDC, Telenor, Telia and 3) were asked to provide a list of their top 10 selling phones from the past year. On the basis of the four lists, 9 phones were selected to ensure difference between manufacturer, type and technology. Professor Gert Frølund Pedersen and team used international accepted methods to measure how the 9 phones compete on the GSM 900, GSM 1800, UMTS 900 and UMTS 2100 standards.
The state of the art laboratory where the study is conducted is radio-dead, meaning that outside radio signals cannot enter, and signals from inside the lab cannot get out. Measurements are made with an artificial head and hand, simulating how a human uses a mobile phone. A call is established, and the signal transmitted from the phone. The signal received by the phone is recorded from each direction. The polarization around the phone is also noted. Measurements with the phone and each type of networking equipment are also conducted. The results are then summarized to the measured value, TIS (Total Isotropic Sensitivity) for the reception. This method is used internationally by 3GPP and CTIA.
While the study provided a uniform testing environment, it is important to remember that an individual's use of the phone can greatly influence the coverage experienced. Additionally, there can be big differences in how the same phone performs on the different standards GSM 900 GSM 1800, UMTS 900, and UMTS 2100.
This year, 2020, more 48-megapixel and 64-megapixel cameras will now officially come into people’s hands
Stepping into 2020, an article published on the Associated Press forecasts 5G, more screen forms, more megapixels, foldables, etc. are the technology innovations that most smartphone manufacturers are expected to prioritize in high-tech investment and continually enhance it in order to obtain the leading market position in terms of the creativity of products.
According to the article, more megapixels is going to be the key trend in 2020s, as standard of a camera nowadays has been of one of the most important elements and features judging a smartphone.
Development of networks and technology has caused very positive impacts on smartphone application software with social APPs springing out in the past few years. Human lifestyle changed accordingly: besides communication, people also share pictures and videos of life moments onto these platforms.
Spending time on social APPs becomes a ‘basic activity’ for people currently. This phenomenon requires a smartphone with high standard camera, resulting in users expecting more from their mobile photography.
Companies try their best to figure out ways to improve the pixel performance in order to meet people’s growing needs. Some devotes time and effort to the front camera; some works on multi-lens. Mobile photography is one of the most important standards when judging a smartphone. Within 20 years, the pixel has improved 640 times, which is a milestone for mobile photography.
Can you imagine that, in 1999, camera of phones was just 100 thousand pixels, with a single camera? Now smartphones can possess 64-megapixel, multiple cameras, thanks to the rapid development of technology. As Sony IMX586 and Samsung GM1 CMOS sensor have come to the market, most of the smartphones in 2019 carry a camera of 48 megapixels.
This year, 2020, more 48-megapixel and 64-megapixel cameras will now officially come into people’s hands. In 2020s, the smartphone industry will undoubtedly embrace a brand-new era of ultra-high pixel.
Once the new generation of this super high definition smartphones put into batch production in 2020, it will trigger the battle of camera pixel amongest the smartphone industry. It could be an indication that companies will competing to bring up new phones with even more powerful cameras, and possibly, even the ‘Billion megapixel’ may soon be brought into reality very soon.• 3/20
