Abstract: Some implementations may provide a method that includes: receiving, at a mobile device, data encoding a first digital watermark present on the identification document; extracting a first portion of personally identifiable information encoded by a spatial luminance pattern associated with the first digital watermark; receiving, at a mobile device, data encoding a second digital watermark present on the identification document; extracting a second portion of personally identifiable information encoded by a spatial luminance pattern associated with the first digital watermark; and validating the identification document based on at least one of the first portion of personally identifiable information or the second portion of personally identifiable information.

Abstract: Some implementations may include a method for watermarking an identification document, the method including: modulating a spatial luminance pattern associated with a first digital watermark to encode a first portion of personally identifiable information; modulating a spatial chrominance distribution associated with a second digital watermark to encode a second portion of the personally identifiable information; and applying the first digital watermark and the second digital watermark to the identification document.

Abstract: In some implementations, a computer-implemented method and system for enrolling customers into a digital identification program may include obtaining, from a digital identification database, customer information that describes a customer, providing to the customer device an access code for activation, receiving a request from the customer device for the digital identification, where the request includes the access code and customer information that describes the customer, providing a request for secure information that describes the customer from a secure information database, receiving the secure information that describes the customer stored in the secure information database, generating the digital identification for the customer based on the secure information and the customer information, and providing the digital identification to the customer device.

Abstract: Some implementations provide a machine-assisted method for screening a person, the method including: receiving, at a scanning device, an identification document presented by the person, the identification document showing a machine-readable code that encodes personally identifiable information of the person, a biometric of the person, and printed information; scanning the machine-readable code on the identification document to extract personally identifiable information of the person; comparing the extracted personally identifiable information against records stored at a database; determining that the extracted personal identifiable information matches a record stored at the database; receiving data encoding the biometric of the person on the identification document for comparison with the person presenting the identification document; receiving a determination that the biometric from the identification document identifies the person presenting the identification document; and determining whether the identifi

Abstract: A steganographic-based ordering system and method using a digital identification (ID) are described. A user may obtain a digital ID card on a user device and select modes for interacting with the vendor. Using the digital ID, the user can create a personal profile that indicates the user's preferences, and place an order for an item (e.g., a product or service) through the digital ID. The order may be steganographically-embedded along with user data within the digital ID. The digital ID including the steganographically-em bedded order is transmitted to a digital ID reader located at the vendor. When completing an order for the user, the digital ID reader may de-embed user and order data from the received digital ID to obtain information about the user and provide more personalized service to complete the order.
