摘要： A computer implemented system and method for managing a stack containing a plurality of documents. The system scans and manages documents provided by the users in form of batches. Multiple users can provide the documents to be managed in form of a stack that contains the documents separated by separating pages and submission forms. The submission forms are then identified by the system to identify the batches and allot track numbers to the identified batches for future reference. Documents within the batches are identified by the separating pages and are allotted barcodes for identification. These documents are scanned and processed to obtain quality checked images of the documents which are then stored in a central repository. The system allows the users to change/set prioritization of a request or document type and also allows automatic indexing, routing of the transactions, processing, quality checking, and modification in the scanned images.

摘要： 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.

摘要： A computer implemented system and method for lightweight authentication on datagram transport for internet of things provides a robust authentication scheme based on challenge-response type of exchanges between two endpoints sharing a pre-shared secret. A symmetric key-based security mechanism is utilized in the present disclosure where key management is integrated with authentication. It provides mutual authentication wherein the end-points in the system are provisioned with a pre-shared secret during a provisioning phase and a client database is provided at the server side for client identification. The system comprises random number generators for generation of nonces, and key generators to generate secret key and session key. The nonces and keys are valid only during the session and thus help in providing secure authentication across sessions.The system can be further adapted on transport layer security protocols like DTLS and can be integrated with application layer protocols like CoAP for constrained devices.

摘要： 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.
