Abstract: A topical anti-microbial composition and use thereof comprising a quaternized chitosan derivative having a polymerizable organic moiety and an amphoteric surfactant.

Abstract: Embodiments are directed towards filtering from a user generated content (UGC) search result those documents determined to have insufficient subject matter specificity as defined by a training of a classification filter. The training comprises selecting a set of UGC that is definable as having sufficient subject matter specificity (a good set), and another set of UGC that is definable as having insufficient subject matter specificity (a bad set). The trained UGC classifier may examine search documents, and based on the documents having values above a defined threshold categorize the document as having sufficient subject matter specificity (or not). Those documents having insufficient subject matter specificity based on their determined thresholds may be filtered out of the submitted UGC search results. The documents remaining within the UGC search results may then be provided to a searcher for display at a client device.

Abstract: A method and system for protecting electronic files by applying a portable access control lock to each electronic file while allowing multi-user access to the protected electronic files across a distributed network is described. The portable access control lock is adapted for implementing a set of complex access control rules that include managing an audit trail for the corresponding protected electronic file.

Abstract: A method and system for strengthening authentication credentials for accessing any number of applications across multiple access interfaces and across multiple remote access sites is disclosed. The applications can be accessed by a set of authorized users by using multiple instances of a predictive scheme for generating and synchronizing the authentication credentials and by leveraging pre-existing infrastructure associated with the applications.
