Abstract: A database is populated for further medical characterization through a world wide network of computers. The database is populated with a plurality of user health information from a plurality of users. The user health information includes genetic data and phenotypic data for a user. The database is populated at least in part through browsing activities of the plurality of users on the world wide network of computers.

Abstract: A secured database is populated with genotypic and phenotypic data using a server coupled with a world wide network of computers. The server provides a web site configured to create trust of the web site by users. Users are invited to submit phenotypic data, and users are invited to submit a biological sample. The secured database is populated with received phenotypic data, and received biological samples are analyzed to obtain genetic data. The secured database is populated with the genetic data obtained from biological samples. Users that previously submitted phenotypic data are prompted to submit new phenotypic data, and the secured database is populated with the received prompted new phenotypic data. The secured database is prompted with received unprompted new phenotypic data.
