Abstract: Determining a next time to communicate via a network with a source of updates is disclosed. In some embodiments, determining a next time to communicate via a network with a source of updates comprises receiving from a request source an update request, and scheduling a next time for the request source to check for updates. In some embodiments, determining a next time to communicate via a network with a source of updates comprises monitoring network communication activity, and in the event anomalous network communication activity is observed, reducing a time remaining until a next check for updates is performed.

Abstract: In some embodiments, techniques for information security include receiving information related to an authentication credential, wherein the information is related to a failed authentication attempt; determining whether the authentication credential is related to a valid account; and performing a security measure related to the valid account, if it is determined that the authentication credential is related to the valid account. In some embodiments, techniques for information security include Determining that an authentication attempt has failed, applying a privacy-performing transformation such as a cryptographic hash or encryption to an authentication credential, and distributing the privacy-preserved credential.

Abstract: In some embodiments, a technique for challenging a message comprises receiving a message, providing a captcha, providing a machine-solvable puzzle, and sending the captcha and the machine-solvable puzzle.

Abstract: In some embodiments, techniques for location processing relating to a route include receiving route data associated with a public transit route, determining a destination related to the route data, determining a current location, determining that the current location is related to the destination, and providing an alert.

Abstract: In some embodiments, techniques for document integrity may include detecting an initiator associated with a key, detecting the end of an HTTP header, determining that no terminator matching the key has been detected, and rejecting the HTTP header. In some embodiments, techniques for document integrity may include generating a key and associating the key with an initiator insertion point and a terminator insertion point.

Abstract: In some embodiments, techniques for filtering electronic messages may include various enhancements.

Abstract: In some embodiments, techniques for location-based services may comprise receiving a first report associated with a mobile phone and with entering a facility, receiving a second report associated with the mobile phone and with exiting the facility, and determining an amount of time during which the mobile phone was associated with the facility based at least in part on data including information relating to a first time associated with the first report and a second time associated with the second report, wherein the amount of time is to be used in calculating a charge on an invoice to a client associated with the facility for a service performed by personnel associated with the mobile phone.

Abstract: In some embodiments, techniques for processing an alert may include receiving a message, wherein the message includes a specification of a first location, creating an alert, associating the specification of the first location with the alert, determining a first current location as a second location, wherein determining the second location follows receiving the specification of the first location and precedes determining a third location, determining that the second location does not match the specification of the first location, determining a second current location as the third location, determining that the third location matches the specification of the first location and presenting information relating to the alert.
