Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for privacy protection. In one aspect, a method includes accessing personally identifiable information (PII) type definitions that characterize PII types; identifying PII type information included in content of a web page, the PII type information being information matching at least one PII type definition; identifying secondary information included in the content of the web page, the secondary information being information that is predefined as being associated with PII type information; determining a risk score from the PII type information and the secondary information; and classifying the web page as a personal information exposure risk if the risk score meets a confidentiality threshold, wherein the personal information exposure risk is indicative of the web page including personally identifiable information.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating activity signatures and detecting activity replays. In one aspect, a method includes accessing activity data first and second activity sequences; generating a first activity sequence signature from the first activity sequence, and generating, for each second activity sequence, a respective second activity sequence signature from the second activity sequence; for each second activity sequence, determining a similarity measure that is a measure of similarity of the first activity sequence to the second activity sequence from the signatures; for each second activity sequence having a similarity measure that meets a threshold, determining that a security violation occurred during the second user session of the second activity sequence; and for each second activity sequence having a similarity measure that does not meet the threshold, determining that a security violation did not occur during the second user session.
