    Abstract: Systems and methods for encoding data in a machine-readable image (e.g., an artificial fingerprint) are disclosed. The methods include segmenting a plurality of bits included in a bit stream to be encoded into a plurality of blocks such that each block includes two or more of the plurality of bits. The plurality of blocks are used to generate a minutiae template comprising a plurality of minutiae points each of which is representative of a local ridge discontinuity in a fingerprint, and is associated with a location and an orientation. An artificial fingerprint is generated from the minutiae template, and stored in association with the bit stream. The artificial fingerprint encodes the bit stream and comprises a plurality of ridges and a plurality of valleys.

    Abstract: A print configuration system will receive, from a first sensing modality, a first message indicating that a user has entered a first region where a print device is located. The system will access a profile for the user to identify a first configuration task, and it will cause the print device to perform the first configuration task. The system will later receive, from a second sensing modality that is different from the first sensing modality, a second message indicating that the user has entered a second region. The second region includes the print device and is a subset of the first region. In response to receiving the second message, the system will cause the print device to perform a second task that is different from the first configuration task.

    Abstract: A printed structure, and systems and methods for creating the printed structure are disclosed. The printed structure includes a substrate, a first printed image layer, and a second printed image layer printed at least partially over the first printed image layer. The first printed image layer includes a first variable image printed using a first electrophoretic ink and the second printed image layer includes a second variable image printed using a second electrophoretic ink. The first variable image and the second variable image are configured to selectively change their display states upon application of an electric field.

    Abstract: Systems and methods of extracting information encoded in a machine-readable image (e.g., an artificial fingerprint) are disclosed. The methods include receiving a machine-readable image and generating a minutiae template from the machine-readable image. The minutiae template includes a plurality of minutiae points, each being representative of a local ridge discontinuity in a human fingerprint. The methods further include identifying, for each of the plurality of minutiae points, a minutia point orientation and a minutia point type, and retrieving, from a data store, a plurality of blocks associated with the identified minutiae point orientations and minutiae point types where each block includes two or more bit values. The retrieved plurality of blocks are concatenated to generate a bit stream encoded in the machine-readable image.
