Abstract: A system and method for maintaining privacy of a user's telephone number is disclosed. The method provides a means by which a user A may prefer to exchange her contact number with another user B. The contact number is encrypted by user A and passed on to the mobile phone of user B. In the phonebook of user B, the contact number of user A is stored in encrypted format. Further, when user B initiates a call to user A, the encrypted number is sent to the network. At the MSC of user B, the number is decrypted and a call is established with user A. When user A calls user B, user A's number is encrypted at user B's MSC. This is transmitted to user B, where it is compared with the already encrypted number in the phonebook. The matching name of user A is then displayed.

Abstract: A remotely controlled biometric based mechanism for security systems includes a remote security lock and uses an Onsite Controller (OC) and a plurality of Remote Controllers (RCs). Further, the OC is located at the site of the lock and the RCs may be located away from the site of the lock. The remote security lock employs 2-factor authentication mechanisms using smartcard access and biometric inputs. Randomized selection of a subset of controllers (RCs) who operate the lock is performed. The randomization enhances the scalability of the system, while keeping the security strength of the system as that of choosing the full set of controllers for operating the lock. A measure for determining the security level is also included, where the measure chosen is the number of controls that need to be broken to gain access to the controlled resource.

Abstract: Embodiments herein provide a method and system for synchronization in a Wireless Communication Network using a new frame, Synchronization Frame (SF), and a configurable length of the same that is transmitted from a Network Controller (NC) to the Network Elements (NEs) in the network. The periodicity of the SF could be changed, to align with the data exchange periodicity, while still keeping synchronization. The length of the SF is made configurable to achieve this effect. It is directly proportional to the period, with which it needs to be transmitted, i.e., a larger delay between two SFs is achievable through the use of a larger SF frame size. This method provides a mechanism in which synchronization between the NC and NEs is achieved by listening to only a part of the SF, which is constant in size. This method also provides tolerance to failure by using acknowledgement schemes.

Abstract: A multiparty controlled remote security lock is disclosed. The embodiments herein relate to security systems and, more particularly, to remotely controlled biometric based mechanisms in security systems. In order to operate the remote security lock at least one OC and a plurality of RCs are employed. Further, the OC is located at the site of the lock and the RCs may be located away from the site of the lock. The remote security lock employs 2-factor authentication mechanisms using smartcard access and biometric means. A method for randomized selection of a subset of controllers (RCs) who operate the lock is used. The randomization enhances the scalability of the system, while keeping the security strength of the system as that of choosing the full set of controllers for operating the lock.
