An image forensics system estimates a camera response function (CRF) associated with a digital image, and compares the estimated CRF to a set of rules and compares the estimated CRF to a known CRF. The known CRF is associated with a make and a model of an image sensing device. The system applies a fusion analysis to results obtained from comparing the estimated CRF to a set of rules and from comparing the estimated CRF to the known CRF, and assesses the integrity of the digital image as a function of the fusion analysis.

A system includes an image processing apparatus and an information processing apparatus that provides a chat service, the image processing apparatus includes a reading unit that reads an image on a document, a memory, and a processor that executes a program stored in the memory to generate a file based on the read image, receive a password from a user, encrypt the generated file, using the received password, and transmit the encrypted file and the received password to the information processing apparatus, wherein the information processing apparatus includes a memory, and a processor that executes a program stored in the memory to cause the information processing apparatus to receive, from the image processing apparatus, the encrypted file and the received password, execute processing for posting the received encrypted file to a channel specified by the user, and execute processing for posting the received password to the channel.

A method for checking the authenticity of products, by checking an image (A) of a product. The proof of authenticity is not visible to the human eye and cannot be copied. This is characterized in that a code stored in a halftone image by manipulation of dots and/or a manipulated field bounded in the halftone image can be read by means of an optical device and compared with a retrievable value in at least one database. In at least one field (F1 to F5) a part of a serial number is determined which describes the structure of the serial number and a hash function used for transmitting the serial number to the database, and this is also characterized in that the serial number is subsequently assembled and encrypted with the corresponding hash function.

A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processor also places the augmented captured information in association with subscriber information in a transmission of the augmented captured information to a receiving facility requiring such subscriber information. A transmitter transmits the transmission including the augmented captured information and the subscriber information to the receiving facility. An encryptor encrypts the augmented captured information with a symmetrical encryption algorithm to provide encrypted augmented captured information in the transmission with the subscriber information.

An image reading apparatus receives, from an information processing apparatus, a scanning request for push scanning for a designated destination, scans an original document and generates image data in response to the scanning request, and transmits, to the destination, a request including authentication information for accessing the destination and the image data, and if a response indicating that an error has occurred in authentication using the authentication information is received, the image reading apparatus saves image data for transmission based on reauthentication and provides a notification of the error to the information processing apparatus. The image reading apparatus transmits, to the destination, a request including authentication information for reauthentication and the saved image data if the authentication information for the reauthentication in response to the notification of the error is received from the information processing apparatus.

In one implementation, a physical version of a document is converted to a digital representation of the physical version and a new certificate is computed for the digital representation of the physical version. The new certificate is computed based on the digital representation of the physical version, at least one processing step performed on the digital representation, and a prior certificate computed for a prior digital representation indicative of the physical version. In another implementation, a document is validated.

A printing management server includes an identification information management unit that manages identification information uniquely associated with an email address assigned to a printer, a print request receiving unit that receives a print request that is a request to print content and that accompanies the identification information, and a print instructing unit that designates an email address, corresponding to the identification information accompanying the print request specified by the identification information management unit, to an email printing server that causes a printer corresponding to a designated email address to execute a print, and instructs the email printing server to cause the printer corresponding to the designated email address to print content included in the print request.

Digital signature authentication systems and methods are disclosed. An example method of authenticating a digital signature extracted from a high resolution image includes comparing an extracted signature from an image to a reference signature. The example method also includes authenticating the extracted signature against the reference signature according to one of a plurality of different authentication protocols.

An information processing device includes a linker that links respective identification information of one or more persons and an object involved in a transfer established using a network, and an updater that updates the respective identification information for a subsequent transfer transaction.

A verification system includes: a code generation server publicizing time stamped codes; a proving device, including a video camera, that acquires a published time stamped code from the code generation server, and, while recording a video, incorporates the acquired time stamped code into the video; and a verifying device that receives the video, extracts the time stamped code from the content of the video, compares the time stamped code to published time stamped codes, and displays a verification of the published time stamped code.
