Fingerprint Recognition in Smartphones

Safety of our belongings has become imperative in this modern society where thefts, frauds and dishonesty are widely prevalent. In the case of smart phones, it is not only necessary to safeguard the device, but also the data stored in it. Mobile phones are not mere telephones intended for communication. The multifarious functions of the device have made it an essential gadget in the modern lifestyle. The sophisticated smart phones are being used to store data regarding confidential transactions, personal banking records and even sensitive information. As such the use of digital personal identification number (PIN) is often found inadequate. A more effective and fool proof method was found wanting. The evolving technology could provide an adequate solution. As in the case of PDAs, biometric security system has been incorporated in the smart phones also.
Fingerprint recognition system is an innovative method to ensure protection of the data saved and stored in the smart phones. It is based on biometrics, a system which applies personal biological data to statistical information to obtain pattern recognition. The biometric option is cost effective, sensitive and accurate. The embedded data based on biometric authentication is used for personal identification. User will be able to operate the keyboard only when the phone identifies the embedded fingerprint of the genuine person to whom it belongs. Electro-optical fingerprint recognition methods successfully scan, compare and identify the genuine smart phone user. The system is considered as an effective alternative for passwords and other conventional safeguards. The touch sensitive mobile handsets with fingerprint capability is now much sought after product, as the users are increasingly saving and storing sensitive data, as mentioned earlier.
Consequent to the market demands, several manufacturers are providing fingerprint recognition to their smart phone products. New finger print verification algorithm has been adapted by the manufacturers to protect and safeguard smart phone data of the users. Consumers are now benefited by the declining price level in the smart phone market. The new fingerprint recognition system integrated to the products is comparatively cheaper but qualitatively superior. All reputed brands of mobile phones available in the market now offer this innovative security option.
Consumers can choose from an array of models which are touch-sensitive and with soft keypads. The newly built-in safeguard is yet another consumer friendly feature incorporated to the all pervasive smart phones.

Haptic Technology In Mobile Phones

The core principle behind the touch screen in mobile phones is haptic technology. Haptic is concerned with the sense of touch and this technology when integrated with mobile phone adds a new dimension to the superior performance of the product. The fact is that many such technologies have contributed to make mobile phone a multi-featured product in tune with the growing expectations of consuming public. When touch screen became a favourite option of smart phone users, it is expected to be a perfect and result oriented feature. Haptic technology when fine tuned to achieve greater capabilities was found to be the right vehicle in this respect. The technology played a vital role in redefining the touch screen concept in the process of hardware re-engineering.
The origin of touch screen interface in mobile phone is from the Japanese experiment with Wacom graphics tablets which involves the pressure area and direction of the touching pen. Earlier touch interfaces were used in the computers. Evolving technology made it possible to extend the use to provide touch screens for mobile phones. But still it took many years to prefect the techniques in order to provide hassle free touchscreen interface to mobile phones. As in the case of any other new venture, there were teething troubles in the early stages. But by the time haptic technology was integrated to iPhones, consumers found that system became foolproof. Today the touch screen interface is considered as an integral factor of smart phones.
The principle, involves the application of pressure by placing user’s finger or a stylus on the screen. All leading manufacturers have introduced their brands of touchscreen interface in smart phones. There are few consumers complaints that the touch screens in mobile gadgets very often develop errors causing hardships to the users. A button on the touch screen is found lacking sensitiveness to alert the user and as such the system is prone to develop errors. But latest products are free from such problems thanks to the development of haptic technology. The user will receive alerts now to ensure that the button is pressed properly.
In the last couple of years touch screen phones have become favourite options of the consumers indicating that haptic technology based touch screen interface could eliminate all the inherent maladies, it had in the initial stages of its introduction. More and more users find haptic technology as convenient when selecting menu options in the process of using the mobile phones.

LTE Technology In Mobile Phones

Evolving technology is taking the mobile phone to new heights in respect of its characteristic features and performance standards. Intended for communication purpose alone at the time of its introduction, the mobile phone has become a multipurpose utility with several features. It is now a telephone, a camera, a computer, a GPS device and much more for the user. Intensive research has resulted in developing the mobile phone with advanced features to cope up with the challenges in this rapidly changing world.
In such a scenario, LTE or Long Term Evolution is a project that is targeting revolutionary changes in the mobile phone technology. It is within the framework of third generation mobile telephony and is expected to improve upon the Universal Mobile Telecommunication standards in order to cope up with future requirements. Improving spectral efficiency, lowering costs, improving services and better integration with other open standards are among the objectives of the project. Known as 3GPP (third generation partnership project) LTE in technical parlance, the project will add new specifications and will formulate innovative ideas and concepts for taking mobile telephony to fourth generation technology. As the improvisation is based on the existing third generation technology, service providers will be able to upgrade their network suitably without incurring exorbitant costs. Alternatively another network based on a different technology will be much more expensive.
Handsets and other mobile devices will be able to download multimedia or information data almost ten times faster than the existing speed under the 3G spectrum, once the LTE project is successfully completed. The user can download mobile Broadband as fast as a computer having wired Broadband connection. As a multi-faceted entity, a mobile phone is being used by the consumer to watch movies, listen to music and also to browse internet. As such the consumers in the given circumstances have high expectations. The demanding consumer in the present scenario would like to download a 700MB movie file in a matter of moments at 100Mbps. LTE technology is capable of meeting such challenges.
All major players in the world mobile phone market have agreed to adhere to the LTE based fourth generation technology. This is a very important factor in the context of global connectivity. Despite diverse view points between operators in the mobile telephony, some sort of consensus is emerging in the matter of standardization. The innovative product is expected to reach the market by 2010.
