Abstract: A computer implemented system and method for extracting and recognizing alphanumeric characters from traffic signs is envisaged. A camera present in the system is adapted to be mounted on the vehicle for capturing images of traffic signs. The system then gives a region of interest (ROI) within the frame of the captured image, from where the alphanumeric characters are extracted and enhanced for recognition. For recognizing the enhanced alphanumeric characters, the image is converted to binary image and morphological thinning technique is applied on it. The space then obtained between two alphanumeric characters thus helps in extracting the characters and recognizing them independently from the captured image. For each extracted alphanumeric character is re-sized to a specified size and is recognized with the help of white pixels count. Once the alphanumeric characters are recognized they are displayed on a display.

Abstract: A system(s) and method(s) for secure session establishment and secure encrypted exchange of data is disclosed. The system satisfies authentication requirement of general networking/communication systems. It provides an easy integration with systems already using schemes like DTLS-PSK. The system follows a cross layer approach in which session establishment is performed in a lightweight higher layer like the application layer. The system then passes resultant parameters of such session establishment including the session keys to a lower layer. The lower layer like the transport layer is then used by the system to perform channel encryption to allow exchange of encrypted data based on a cross layer approach, over a secure session. As the exchange of data becomes the responsibility of the lower layer like the transport layer, the data is protected from replay attacks since the transport layer record encryption mechanism provides that kind of protection.

Abstract: A computer implemented system and method for providing users with secured access to application servers have been disclosed. The system and method envisaged by the present disclosure are not restricted to providing users with secured access to application servers. The system and the method also ensure that transactions performed by the users through the application servers remain secured and hack-resistant. The present disclosure envisages a system that acts as a secured, trusted gateway between the users and the application servers associated with providers of sensitive services such as banking and financial institutions. In case of the system envisaged by the present disclosure, rather than directly accessing an application server, users are made to contact the system of the disclosure and upon verification of their respective identities, are allowed to access the application servers associated with providers of sensitive services.

Abstract: A computer implemented system and method for generating and recovering an authorization code. The system creates an authorization code by accepting a base-sentence from a user. Based on the characters present in this base-sentence, the system computes a base-sentence matrix. The system also generates a plurality of patterns. The user can either select the pattern from the multiple patterns suggested by the system or can create his/her own pattern. The system then performs multiplications between the base-sentence matrix and the selected pattern matrix at different stages in the path forward, for obtaining a strong authorization code. In case the user forgets the base sentence, the system also has provisions to manage forgotten authorization code. This is done by fragmenting the base-sentence into different matrices and storing the fragmented matrices into a repository after computing matrix multiplication with a security question answer and with a secret key provided by the user.

Abstract: A method and system for blind audio watermarking has been envisaged. The system embeds an in-audible watermark by modifying a predetermined singular value in the wavelet domain. The generated watermarked audio signals are robust again Gaussian noise and other watermark removal and compression attacks. Also, the system can perform watermark extraction/detection in real-time without requiring in advance, either the original audio signal or its processed parameters. Thereby, the method and system provide a real-time, efficient technique for blind audio watermarking.

Abstract: A system and method for online authentication having at least two levels of authentication has been disclosed. The two levels of authentication provide total security of privileged information by requiring users to authenticate themselves in two stages/levels.

The graphical password verification is based on the novel concept of challenging users with a dotted grid to enable users to create a non-definable vector pattern of definitive lines by sequentially joining pre-determined dots in the grid.
