| 摘要 | Digital Cameras configured to verify authenticity of digital photos taken with the digital camera and related methods and computer program products are provided. GPS information associated with a photograph taken with the digital camera is obtained. A checksum of pixels that make up the photograph and the obtained GPS information is generated. The generated checksum is encrypted using a private key associated with the digital camera so as to allow verification that the photograph has not been modified. | ||

| 主权项 | 1. A digital camera comprising: a global positioning system receiver configured to obtain global positioning system information associated with a photograph taken with the digital camera; a checksum module configured to: generate a first checksum of pixels that make up the photograph and store the first checksum in metadata associated with the photograph; and thengenerate a second checksum of the first checksum and the global positioning system information; and an encryption module configured to encrypt the checksum using a private key associated with the digital camera to provide an encrypted checksum so as to allow verification that the photograph has not been modified, wherein the encryption module is configured to encrypt the second checksum using the private key to provide the encrypted checksum. | ||
