BIOMETRIC ACCESS CONTROL SOFTWARE FOR MOBILE TELEPHONES WITH BUILT IN CAMERAS
SecurePhone is a biometric access control system for mobile telephones, protecting against unauthorised access to personal information using the latest facial recognition technology. As a platform for this application, all camera equipped mobile telephones based on Symbian 7.0 can be used.
UNIQUENESS
In today's mobile telephone software market, there are a great deal of applications for storing personal information.
SecurePhone is different from others due to its use of biometric facial identification technology to control access to personal information. Using the latest facial recognition technology, telephones can easily become a secure repository for:
• Personal telephone directories.
• Credit card information.
• PIN codes & Passwords.
• Confidential text.
HIGH DATA SECURITY
Reliable protection against unauthorised access to the personal information of the owner is provided by the biometric facial identification system. In contrast to the conventional use of passwords and PIN codes which may be forgotten, disclosed, lost, or stolen, using the information protection biometric code, the protected data can not be used without the telephone owner's involvement (e.g. the mobile telephone is lost).
EXPANDABILITY
SecurePhone is easily expandable and may be customised at the customer's request.
USER FRIENDLINESS
SecurePhone has a user-friendly interface and navigation, working with the application is simple and easy-to-see. Basic functions are accompanied voice and visual messages.
FUNCTIONAL SPECIFICATION
SecurePhone consist of rich layer of application protected by the biometric access control software in addition to an authentication layer for managing users and fine-tuning the recognition engine.
APPLICATION LAYER
SecurePhone has built-in applications that ensure the confidential storage of the user’s information:
Telephone Directory - intended for the storage of telephone numbers and contacts.
The “Telephone Directory” Application has the following functions:
- Creation, storage and editing of contact information about people (personal data, telephone numbers, etc.).
- Viewing contact information.
- Navigation and search functions.
- Deletion of contact information.
Daily Log - intended for storage of text information, allowing task and business planning.
The “Daily Log” Application has the following functions:
- Creation, storage and editing of text information (notes, tasks, etc.).
- Setting data when entering information.
- Viewing of information entry.
- Navigation and search functions.
- Deletion of information entry.
Password Catalogue - intended for the storage of different passwords.
The “Password Catalogue” Application has the following functions:
- Creation, storage and editing of information about passwords (password, type of password).
- Viewing of password information.
- Navigation and search functions.
- Deletion of password information.
Credit Card Directory - intended for the storage of credit card numbers and PIN codes.
The “Credit Card” Application has the following functions:
- Creation, storage and editing of information about credit cards (number, PIN code, type, validity).
- Viewing of credit card information.
- Navigation and search functions.
- Deletion of credit card information.
AUTHENTICATION LAYER
The authentication layer consists of the facial recognition engine and its operational parameters as set by the user. Following function are performed within this layer:
Administration:
- Creating, editing and deleting user accounts;
- Saving digital images in the camera picture gallery of users.
Selection of security levels:
- Access by code only;
- Access by biometric face verification only;
- Access using both methods.
Access control function:
- Code verification;
- Facial identification;
- Access granting or denial.
Tuning for recognition performance improvements:
- System basic training;
- System additional training;
- Database optimisation.
Biometric identification enrolment consists of three stages:
Basic Enrolment. Includes preparation and processing of 8 photographs of the users under equal lighting conditions. 8 pictures are expected to be taken, each with the same camera/subject orientation but each taken with a 45° offset until both camera and subject have turned a full circle. This should be performed in a single place in a room near a light source, preferably near a window. The purpose is to obtain a set of photographs with different light angle and levels. All these pictures will automatically become enrolment samples. Usually after this process, the probability of true identification (in full version) is over 70%, and less than 0.000001% for the probability of false identification.
Additional Enrolment.
At this stage, the system trains itself. The system is set for both identification and enrolment (in addition to enrolment samples). In case some new attempt to identify fails (too low coefficient of coincidence), the system will display the obtained image onscreen, and suggest that the user add this image to the enrolment samples, or reject it. As a result, the system will reach the level of accurate identification TAR (True Accept Rate) ~ 100%.
Database Optimisation.
This is initiated by the user after a long series of successful identifications during “Additional Enrolment”. As a result, the database will be optimised, and the system's TAR will be equal to 100%. The system is ready for operation.
To make it more convenient, the authentication system is accompanied by voice and visual messages.
BIOMETRIC TECHNICAL PERFORMANCE
The biometric engine of SecurePhone is available in two versions:
Standard version
Time of verification:
3-5 seconds
False identification probability:
4 errors out of 1,000 identifications
|
Professional version
Time of verification:
3-5 seconds
False identification probability:
1 error out of 1,000,000 identifications
|
Both versions are supplied with a complete set of documentation including a user manual.
