BioWallet is basically a “safe wallet” that can store sensitive information (passwords, certificates, documents, conversations, notes, pictures, etc.). This information can only be accessed by the user through iris or handwritten signature based authentication. The data is kept secret even if the device is lost or stolen using strong biometric encryption techniques. Advanced users can also digitally sign their documents or encrypt their communications. Even the phone itself can be protected and unlocked only if the user presents his/her eye or signature.

Iris Recognition is one of the most reliable biometric methods. This feature uses the Android camera API to accomplish hardware independence making it possible for biometric methods related to the camera (iris, face, etc.) to work properly on all compliant devices.

Although it is not as precise as iris based recognition, handwritten signature recognition is widely accepted as a method to prove your identity and it is easier to use. It is implemented using the Android touch screen API that gives complete information about the touch events (position, pressure, velocity, etc.)BioWallet can be used as an “electronic wallet” to store sensitive information. The documents can also be encrypted, decrypted, digitally signed and verified. This is possible thanks to the support of the Android platform that provides a powerful relational database (SQLite) and cryptographic capabilities.

While the user is using the Android phone, B4E lets the user obtain multimedia information based on the external environment and the user’s profile. B4E also allows the user to learn about recent disasters, so that the user can donate money to the NPO or NGO if they wish.

B4E uses Android’s multithreading mechanism to handle different events including both computation-bound (processing the multimedia data) and I/O-bound (accessing the Internet connection and local files) without compromising B4E’s responsiveness to users’ inputs.

B4E extracts a user’s identity and friends’ data from their SIM card and phonebook through Android’s API so that the user can input less data, go through fewer steps, and ultimately have a better experience with B4E.

Teradesk is a virtual file storage and remote file access tool. User files are stored and controlled by the Teradesk Server and transferred in encrypted form to and from the cellphone. Teradesk allows transfers of any size with pause control, resume and full recovery of broken transfers. Whether your battery life ended or your Internet connection crashed there will be no data loss. Smart features permit total control over user disk space and content including hierarchical and relational navigation, file sharing, file versioning, comments on files and folders, GoogleDocs integration and remote access to other devices and computers running Teradesk.

Teradesk takes advantage of the background processing and networking capabilities of Android to allow multiple encrypted background transfers of any type and size. If the device claims resources and stops the application, the next time Teradesk is activated it will notify the user about pending transfers thus allowing them to be restarted from the breaking point.

Bluetooth and MMS APIs of Android allow Teradesk to send files direct from the storage to cellphones and bluetooth enabled devices of any person. In addition, Teradesk can browse and get files from home/office computers and other Android cellphones.

Allows users to preview and visualize stored images without the need to download each one to the cellphone file system. GoogleDocs integration allows a document, spreadsheet or presentation file to be converted and uploaded to a GoogleDocs Server. After conversion, users can read or edit documents online using the Android built-in Internet browser.

Piggyback improves and brings simplicity to carpooling by providing several benefits over traditional systems such as real-time or planned trip management with automated and secure transactions between drivers and passengers after accurate ride-matching. As a driver, simply input your destination and number of available seats and you’ll be notified when passengers have been found, along with information such as total time, detour length, and savings amount. You are then free to accept or reject those users. On the other hand, passengers will visualize up to ten drivers to choose from, according to their current location and destination, trip price and ratings.

Passengers waiting for pickup can identify their driver simply by visualizing the car’s position, which is updated regularly, and the map zooms in as the car gets closer to the passenger. To further improve identification, the photo and license plate number are also displayed. After Piggyback has calculated routes, drivers will be able to rely on their GPS and Maps API for guidance to pickup locations.

Passengers and Drivers don’t have to argue over the price of each ride since everything is automatically calculated thanks to our algorithm, while financial transactions are processed monthly through the secure platform Paypal.

A system of ratings has also been implemented which ensures that unreliable individuals are evicted from the pool of users. Drivers and passengers rate each other on various criteria such as punctuality, car cleanliness, driving abilities, and “empathy factor”.
