Abstract: The present description refers to a computer implemented method, computer program product, and computer system for receiving a resource request at a representational state transfer (REST) client from a user, the resource request including a user ID, determining, by the REST client, a key pair including a public key and a corresponding private key that are associated with the user ID, obtaining, by the REST client, a certificate associated with the user ID that is signed by a certificate authority and based on at least the user ID and the public key associated with the user ID, impersonating, by the REST client, the user to a REST server using the certificate and the private key associated with the user ID, and accessing, by the REST client on behalf of the user, using a stateless protocol with the REST server, the requested resource.

Abstract: A method for user registration may include in response to receiving registration data of the user from a client, creating an inactivated user account, generating a temporary session that includes a temporary session identification, transmitting the temporary session identification to the client, and subsequent to the transmitting the temporary session identification, sending an e-mail containing a hyperlink for verification to the user.

Abstract: An input handler may receive a request, from a user of a client computer, for credential-based access to a server-based resource. An image map generator may determine a mapping between elements of an image map and secure transmission codes. A code generator may provide, to a user interface of the client computer, the mapping together with rendering code for rendering the image map. A mapping module may receive a sequence of the transmission codes from the user interface after a rendering of the image map by the user interface using the rendering code, based on a selection of image map elements by the user. The selected image map elements may represent the user credentials, and the sequence may correspond by way of the mapping to the selected image map elements and thus to the credentials.

Abstract: Systems and techniques to access data in a computer system provide centralized data storage management for facilitating access to a plurality of different data repositories. In general, in one implementation, the technique includes sending a data access request to a data storage manager and identifying at least one of a plurality of repositories for satisfying the data access request. The repositories may be of different types. In addition, data may be partitioned among the repositories according to data object types and/or attribute characteristics. Once an appropriate repository is identified, the data access request is fulfilled using the identified repository.
