  • Patent number: 10515266
    Abstract: Disclosed herein are system, method, and computer program product embodiments for verifying a document. An embodiment operates by receiving an initial image of a document and identifying a first imperfection on a feature of the document. Thereafter, the feature of the initial image is segmented into a first and second partially overlapping segment corresponding to a first and second portion of the feature, respectively. Subsequently, the feature's first portion is determined to be free from the first imperfection, and the first imperfection is identified in the feature's second segment. After receiving a second image of the document including the feature's second portion, the feature's second portion in the second image is determined to be free from a second imperfection. As a result, an image of the feature is created based on the first and second portions of the feature derived from the initial and second images, respectively.

  • Patent number: 10356353
    Abstract: A solid-state imaging device having a pixel portion in which a plurality of pixels each including a photodiode are arranged in rows and columns, a reading part for reading pixel signals from the pixel portion, and a key generation part which generates a unique key by using, as the key generation-use data, at least one of fluctuation information of pixels and fluctuation information of the reading part, wherein the key generation part includes a tamper resistance enhancement processing part for processing the key generation-use data to enhance the tamper resistance making it difficult to break the unique key as tamper resistance enhancement processing. Due to this, a unique key having a high confidentiality can be generated. Further, reproducibility and uniqueness of the unique ID can be improved to secure a high tamper resistance of the unique key, and tampering and forgery of an image can be reliably prevented.
