Software verification system and methods
View Patent ↗A method for detecting a confirmation of a properly installed software product on a computing device, determining the software product installation properties of the properly installed software product, and storing information relating to at least one or more software product installation properties of the properly installed software product.
1. A method comprising:
(a) providing a computer program comprising instructions for generating a product definition for a software product and validating installations of that software product using the generated product definition;
(b) loading the computer program at a first computer having a first installation of a first software product installed thereon;
(c) executing, using a processor of the first computer, instructions of the computer program which generate a first product definition for the first installation of the first software product installed on the first computer, such generation including
(i) generating, for each file of the first installation on the first computer which includes a version number, a hash value for that respective file,
(ii) generating information about registry entries on the first computer for the first software product;
(d) loading the computer program at a second computer having a second installation of the first software product installed thereon; and
(e) executing, using a processor of the second computer, instructions of the computer program which attempt to validate the second installation, such validation including
(i) comparing the generated hash values for the first installation to generated hash values for the second installation, and
(ii) comparing the generated information about registry entries on the first computer for the first software product to registry entries on the second computer for the first software product.
2. The method of claim 1 , wherein generating, for each file of the first installation on the first computer which includes a version number, a hash value for that respective file comprises generating an MD5 hash value.
3. The method of claim 1 , wherein, with respect to executing, using a processor of the first computer, instructions of the computer program which generate a first product definition for the first installation of the first software product installed on the first computer, such generation comprises generating information about a database object.
4. The method of claim 1 , wherein, with respect to executing, using a processor of the first computer, instructions of the computer program which generate a first product definition for the first installation of the first software product installed on the first computer, such generation comprises generating information about a table.
5. The method of claim 1 , wherein, with respect to executing, using a processor of the first computer, instructions of the computer program which generate a first product definition for the first installation of the first software product installed on the first computer, such generation comprises utilizing information about a last modified time of a file.
6. The method of claim 1 , wherein, with respect to executing, using a processor of the first computer, instructions of the computer program which generate a first product definition for the first installation of the first software product installed on the first computer, such generation comprises setting a flag to indicate whether a file is optional.
