Abstract: Providing information about digital certificate validity includes ascertaining digital certificate validity status for each of a plurality of digital certificates in a set of digital certificates, generating a plurality of artificially pre-computed messages about the validity status of at least a subset of the set of digital certificate of the plurality of digital certificates, where at least one of the messages indicates validity status of more than one digital certificate and digitally signing the artificially pre-computed messages to provide OCSP format responses that respond to OCSP queries about specific digital certificates in the set of digital certificates, where at least one digital signature is used in connection with an OCSP format response for more than one digital certificate. Generating and digitally signing may occur prior to any OCSP queries that are answered by any of the OCSP format responses.

Abstract: Logging events associated with accessing an area includes recording an event associated with accessing the area to provide an event recording and authenticating at least the event recording to provide an authenticated recording. Recording an event may include recording a time of the event. Recording an event may include recording a type of event. The event may be an attempt to access the area. Recording an event may include recording credentials/proofs used in connection with the attempt to access the area. Recording an event may include recording a result of the attempt. Recording an event may include recording the existence of data other than the credentials/proofs indicating that access should be denied. Recording an event may include recording additional data related to the area. Authenticating the recording may include digitally signing the recording.

Abstract: A system and method are disclosed for controlling physical access through a digital certificate validation process that works with standard certificate formats and that enables a certifying authority (CA) to prove the validity status of each certificate C at any time interval (e.g., every day, hour, or minute) starting with C's issue date, D1. C's time granularity may be specified within the certificate itself, unless it is the same for all certificates. For example, all certificates may have a one-day granularity with each certificate expires 365 days after issuance. Given certain initial inputs provided by the CA, a one-way hash function is utilized to compute values of a specified byte size that are included on the digital certificate and to compute other values that are kept secret and used in the validation process.

Abstract: Identifying at least one object in data for photographed images includes detecting a reference pattern in the data, locating the reference pattern in a table of patterns, and identifying the at least one object according to the reference pattern. The pattern may be located on the at least one object. The at least one object may be a greeting card. The pattern may categorize the greeting card by season and/or occasion. The pattern may identify a sender of the greeting card. The pattern may be provided on an item that is separate from the at least one object. The table of patterns may include a record for at least some of the patterns and the record may include additional information associated with the pattern. The additional information may include tasks that are performed in connection with the pattern. The additional information may include geometric and color parameters of the pattern.

Abstract: Adjusting data for photographed images includes detecting a reference image in the data, where the reference image contains a detectable uniformity and adjusting the data according to the reference image. The reference image may be a uniform grid pattern of dots preprinted on paper. A paper type may be determined prior to adjusting the data according to the reference image. The paper type may be determined according to spacing and/or patterns of the dots, and/or layout of page areas covered with dots. Adjusting the data may include removing effects corresponding to a folded corner, a removed corner, an obstructed corner, lens flare spots, and/or a shadow. Positional coordinates of the data may be adjusted by normalizing the grid through a non-linear transformation that eliminates curvature of the grid and/or distortions based on perspective.

Abstract: Extracting an optimal subset of facial photographs includes obtaining an initial set of facial photographs, removing from the initial set photographs any photographs that are of unacceptable quality, grouping a remaining set of photographs according to view angle, removing from the remaining set of photographs any photographs having an undesirable facial expression to provide a limited set of representative facial photographs, and, selecting, from the limited set of facial photographs, an optimal subset of facial photographs. Obtaining the initial set of photographs may include using a video camera while diversifying view angles and controlling recording quality. Obtaining the initial set of photographs may include obtaining a series of still images. The still images may be self-recorded by a person with a smartphone front-facing camera.

Abstract: Indicating data currentness includes, on any date of a sequence of dates, issuing a proof indicating the currentness status of the data during a particular time interval. The proof may be a digital signature. The time interval may be in the form of a current date and an amount of time. The proof may include a digital signature of the time interval. The proof may include a digital signature of the time interval and the data. The proof may include a digital signature of the time interval and a compact form of the data, such as a hash. Indicating data currentness may also include distributing the proofs to a plurality of unsecure units that respond to requests by users for the proofs. Indicating data currentness may also include gathering a plurality of separate pieces of data and providing a single proof for the separate pieces of data. The data may be electronic documents.
