摘要： A data transfer device for transferring data to a removable data storage item. The data transfer device receives content data to be stored to the removable data storage item, encrypts the content data using an encryption key, and transforms at least one of predetermined reference data and the encryption key. The data transfer device also encrypts the transformed predetermined reference data using the encryption key or encrypts the predetermined reference data using the transformed encryption key, and then stores the encrypted content data and the encrypted transformed/predetermined reference data to the removable data storage item.

摘要： An authenticated encryption method and apparatus are described in which plaintext data is encrypted, using a secret key, to form ciphertext data. A message authentication code, MAC, is also formed in dependence on a combination of the ciphertext data and data characteristic of the plaintext data. The ciphertext data and the MAC are then output, for example, for storage to a storage medium. In a preferred embodiment a block cipher operating in GCM mode is adapted to cause the stored message authentication code to be dependent on the plaintext data.

摘要： A workflow order is created for the object. Public parameters are received from a key generation center at a computer associated with an object master. A public key is generated at the computer system based on a user identifier and the public parameters, wherein the user identifier is comprised of user related information. The object is encrypted using the public key such that the object cannot be opened without the a private key, wherein the object is a composite document comprising multiple elements of documents of different formats, and wherein the private key is generated in response to a request from an authenticated user using the user identifier at the key generation center. Access to the multiple elements of the object is controlled based on workflow order.

摘要： A data provider provides and proves an association between a first data value A and a second data value B. The data provider computes evidence E of an association between A and B and ensures that a verifier has A, B and E. The data provider then runs an interactive proof with the verifier to convince the verifier that the evidence is valid evidence of an association between A and B, but without enabling the verifier to provide proof of the validity of the evidence to a third party.

摘要： Systems and methods for adapting images for substantially optimal presentation by heterogeneous client display sizes are described. In one aspect, an image is modeled with respect to multiple visual attentions to generate respective attention objects for each of the visual attentions. For each of one or more image adaptation schemes, an objective measure of information fidelity (IF) is determined for a region R of the image. The objective measures are determined as a function of a resource constraint of the display device and as a function of a weighted sum of IF of each attention object in the region R. A substantially optimal adaptation scheme is then selected as a function of the calculated objective measures. The image is then adapted via the selected substantially optimal adaptation scheme to generate an adapted image as a function of at least the target area of the client display.
