A system and method include obtaining and authenticating image files from users such as insured users at the request of an entity such as an insurance provider. The requesting entity may supply an electronic address of the user and a unique identifier. The system may transmit a link to the electronic address. When selected, the link causes an image authentication application to be installed on a user device. The application takes the images securely and separately from a native camera application. Each image authentication application may be customized for each requesting entity. The authentication server may identify the requesting entity that made the request and identify a corresponding image authentication application to be provided to the electronic address. The images from the image authentication application may be authenticated via reverse image search, time, geolocation, and/or other information. The authenticated images and/or related data may be provided to the requesting entity.

A system includes circuitry configured to embed a digital watermark data in an original image, wherein the original image is divided into a plurality of blocks each block having been embedded with a pattern corresponding to each value of the digital watermark data, store, in a memory, the original image, the digital watermark data embedded in the original image, and an embedding position of the pattern of the digital watermark data in association, detect a pattern in a scanned image of a printed matter, decode the detected pattern to acquire digital watermark data included in the scanned image, align each block between the original image and the scanned image, based on the embedding position of the pattern associated with the original image and a detection position of the pattern detected from the scanned image, and obtain a difference between the original image and the scanned image aligned with each other.

A system and method for producing vision data that is embedded with a blockchain hash stored on a blockchain, the method including: detecting a vehicle event at a vehicle using vehicle electronics included in the vehicle; sending a vehicle event report message to a blockchain domain server in response to the detected vehicle event, the vehicle event report message including information pertaining to the detected vehicle event, and wherein the blockchain domain server is configured to record the detected vehicle event as a part of a blockchain based on the vehicle event report message; receiving a blockchain hash at the vehicle from the blockchain domain server; and embedding the blockchain hash within vision data at the vehicle using the vehicle electronics, wherein the vision data is captured by a vision sensor that is mounted on the vehicle and included as a part of the vehicle electronics.

Methods and apparatuses for watermark embedding and extracting are provided. A method for watermark embedding includes obtaining a carrier object and watermark information to be embedded in the carrier object; generating at least one encoding region including the watermark information according to the watermark information, the at least one encoding region including a plurality of template lattices; obtaining a watermark image according to the at least one encoding region; and embedding the watermark image in the carrier object.

Ability information about an authentication printing function to be transmitted from a printing apparatus to a print client is varied depending on whether a communication path between the apparatuses is encrypted.

Embodiments described herein provide a computer-implemented method of creating a digest of a document. The document to be processed and analysed may be a physical document, or it may already be in a digital form. In the case of starting from a physical document, the document is first scanned, so as to obtain an image of the document. The digital document is then processed using an algorithm or function to obtain one or more datasets comprising a plurality of position independent values. Each of the datasets may correspond to a different line of text or field of text within the document. The one or more datasets are then encoded, the encoded data being used to generate a digest associated with the document, and wherein the digest comprises a plurality of short hashes corresponding to each dataset. The generated digest can then be used to print a digital signature on the document, which can be used to later verify the authenticity of the document or a copy thereof.

A data processing device includes an image data receiving section that receives image data, a data conversion section that converts the image data received by the image data receiving section into data having a format different from a format of the received image data, and a hash value generation section that generates a hash value of the data obtained by conversion of the data conversion section from the received image data.

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.
