摘要： The present invention discloses a method of verifying the authenticity of a provided signature, comprising the steps of: receiving a set of sampled data points, each sampled data point being associated with a different position along the signature; identifying a set of characterizing nodes within the set of sampled data points using a set of predetermined characterizing nodes comprised in a pre-stored user profile; determining if each identified characterizing node lies within a predetermined threshold range of a corresponding predetermined characterizing node; and generating a positive verification when the characterizing nodes lie within the predetermined threshold range. A system arranged to carry out the method is also disclosed.

摘要： A method of encoding content data into a digital image includes determining bit values of a pixel within the digital image, and modifying the bit values within the pixel based on content data to be encoded in order to encode the content data into the digital image. The step of determining the bit values of a pixel within the digital image includes determining a binary representation of the bit values of the pixel. The step of modifying the bit values includes determining a binary representation of the content data to be encoded within the pixel and encoding the content data using a reversible binary operation.

摘要： A method of verifying the identity of a user at an authentication server that includes receiving user data relating to a signature gesture entered by a user at a computing device, the user data having a plurality of sample points, verifying the user data at the authentication server by comparing to reference signature data, encoding a verification message within a digital image, and notifying the user that their identity has been verified on the basis of the user data received from the computing device.
