Abstract
Methods, apparatuses and products are provided for establishing and verifying the authenticity of data within one or more data files. In accordance with one aspect of the present invention, a method for verifying the authenticity of data involves providing at least one data file which includes an identifier and a signature file which includes the identifier for the data file as well as a digital signature. The digital signature is then verified using a computer system, and the identifier in the data file is compared with the identifier in the signature file using the computer system. In one embodiment, the identifier for the data file includes at least one certificate authority, site certificate, software publisher identifier, or a site name, and verifying the authenticity of data involves setting a security level for at least one of the certificate authority, the site certificate, the software publisher identifier, and the site name.
