Abstract: Systems and methods for streaming images are described. A venue seat map is accessed from a data store. A current status of seats rendered in the seat map is accessed from memory. The seat map is updated to indicate the current status. A video stream comprising frames is generated, using a real time protocol, comprising the updated seat map indicating the current status of seats rendered in the seat map. The updated seat map is streamed in real time via the video stream to user device clients. A selection of a seat via the updated seat map is received via a message. A seat token for the selected seat is associated in memory with user. The seat map is updated to indicate a change in status of the selected seat in the seat map. The updated seat map is streamed as a video stream to clients hosted on user devices.

Abstract: Aspects of the present disclosure relate to receiving a request from a remote device for access to an online computer-based service, transmitting to the remote device a request for a verifiable token encoding a verifiable credential containing an issuer's digital signature signed with a private key and an identifier indicating that a holder of the verifiable credential is human. If the verifiable token was not received, access to the online computer-based service is inhibited. If the verifiable token is received, its validity is confirmed utilizing an associated public key. If the validity is confirmed, the request from the remote device for access to the online computer-based service is determined to be from a human and the remote device is enabled to access the online computer-based service.

Abstract: A system of enhancing biometric analysis matching utilizes an image sensor, such as a digital camera, to capture an image of a face of a person. The system may perform image enhancement, such as edge and contrast enhancement, prior to performing face matching. The enhancement may be localized to a given image region based on determined region illumination. The system may perform image processing and analysis comprising face detection, alignment, feature extraction, and recognition. A biometric recognition confidence indicator may be generated using the results of the image enhancement and analysis. At least partly in response to the biometric recognition confidence indicator falling below a threshold enhancing recognition confidence using an image of visual indicia captured using the image sensor.

Abstract: A physical location access control system is configured to receive. via a network interface, a request to provide a temporary access right for a first physical location to a first user, the request providing an indication as to a first time period associated with the temporary access right. In response to determining that the requester has an access right to the first physical location for a second time period that comprises the first time period, a temporary access token corresponding to the first time period is created and the requester's access right to access the first physical location for the first time period is disabled. The temporary access token is transmitted to a device associated with the first user, enabling the first user to access the first physical location during the first time period.

Abstract: Methods and systems are described for performing multifactor authentication. An authentication code may be encrypted in optical indica. Optionally, Advanced Encryption Standard (AES), Rivest-Shamir-Adleman (RSA), DES (Data Encryption Standard), and/or a hashing function may be utilized to encrypt the authentication code. An image of the authentication code may be captured from a device having a display using a digital camera. The image may be in a compressed format and transmitted over a network to an image analysis system. The image analysis system may decode the optical indicia to obtain the encoded authentication data and may perform decryption on the decoded data. If a hashing function is utilized to encrypt the authentication data, the encoded authentication data may be compared to a hash of stored authentication data. If needed, the image analysis system may perform image enhancement prior to performing decoding, including contrast enhancement, deblurring, and/or image rotation.
