摘要： According to one example, there is provided a method of generating a security feature that encodes data. The method comprises obtaining an n-bit code of data to encode, generating an arrangement of dots, designating a first portion of the dots as reference dots and a second portion of the dots as encoding dots, and moving a group of the designated encoding dots by a predetermined direction in a predetermined amount to encode the n-bit code of data.

摘要： An apparatus stores a one-time pad key. Responsive to receiving local input from a user requesting a cryptographic key, via input hardware of the apparatus, the apparatus generates the requested cryptographic key from an unused portion of the one-time pad key. The apparatus provides the generated cryptographic key to a mobile device of the user, via output hardware of the apparatus.

摘要： A forensic verification system (700) extracts a print signature via print signature extractor (710) from the boundary of a halftone contained in an image. The system (700) compares the print signature to a reference signature stored in a registry via comparator (720) to determine differences between the print signature and the reference signature. The system (700) performs a forensic-level statistical image analysis via forensic analyzer (730) on the print signature and the reference signature based on the comparison to authenticate the printed media.

摘要： Document copying systems and methods include initiating a copy job (20) for copying a document (1) having document content. A log (22) of the copy job is generated, and the document is scanned to create a document content image (24). The log is encoded using an input image to produce a data-bearing halftone image (26) which is merged with the document content image (28). The merged data-bearing halftone image and the document content image are printed (30) to produce a copy (2) of the document.

摘要： A forensic verification system (900) extracts a print signature via a print signature extractor (910) from a captured image of a printed halftone. The system (900) utilizes a comparator (920) to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system (900) utilizes a forensic analyzer (930) to perform a forensic analysis on the signatures based on the comparison to authenticate the printed halftone.

摘要： Candidate redeye areas (24) are determined in an input image (20). In this process, a respective set of one or more redeye metric values (28) is associated with each of the candidate redeye areas (24). Candidate face areas (30) are ascertained in the input image (20). In this process, a respective set of one or more face metric values (34) is associated with each of the candidate face areas (30). A respective joint metric vector (78) is assigned to each of the candidate redeye areas (24). The joint metric vector (78) includes metric values that are derived from the respective set of redeye metric values (28) and the set of face metric values (34) associated with a selected one of the candidate face areas (30). Each of one or more of the candidate redeye areas (24) is classified as either a redeye artifact or a non-redeye artifact based on the respective joint metric vector (78) assigned to the candidate redeye area (24).
