A notarization system for use in notarizing a document, the system comprising: a handheld notarization device having a printer; and a notarization application configured to be accessible only by a primary user and to operate on a mobile device having a camera, the notarization application being programmed to digitally read identification information from an identification card of a secondary user received via the camera, such that to verify the identity of the secondary user and authenticate the identification card, digitally scan and generate a digital line drawing of a fingerprint of the secondary user received via the camera, digitally generate a notarization endorsement and cause a printing of the notarization endorsement onto a tamper-resistant sticker via the printer, wherein, when the notarization application is being accessed by the primary user, and upon signing of the document by the secondary user, the notarization application causes a printing of the notarization endorsement.

A system, method, and computer program product for implementing electronically generated promotion deployment is provided. The method includes receiving electronic data comprising shipment identification for a shipment of an item from a shipping client to a recipient. Specialized programable software code is generated and a resulting profile is generated for the recipient. A visible promotional structure associated with a package comprising the shipment is generated and presented during delivery of the package. Generating the visible promotional structure may include generating a physical structure or a digital structure.

The present disclosure provides a method and control apparatus for burning an address code of LED lamp beads, and relates to the technical field of LEDs. The method for burning the address code of the LED lamp beads described by the present disclosure is applied to a burner and includes: generating, by the burner, an optical signal; and sending the optical signal to the LED lamp beads such that the LED lamp beads sense the optical signal, convert the optical signal into an address code and store the address code. The present disclosure makes use of a light sensing effect of the LED lamp beads, sends the optical signal to the LED lamp beads through the burner such that the LED lamp beads generate an address code according to the optical signal, and burn the address code into the LED lamp beads.

Example methods, systems, and apparatuses for verifying a printed indicium are provided. An example method may include receiving a captured image of a print media comprising the printed indicium; extracting a quiet zone grade portion from the captured image, where the quiet zone grade portion includes a printed indicium area of the printed indicium and at least one quiet zone area adjacent to the printed indicium area; in response to receiving a user input providing an overwrite quiet zone requirement indication and determining that the at least one quiet zone area does not satisfy at least one quiet zone requirement, causing at least one of adjusting the at least one quiet zone requirement to at least one reduced quiet zone requirement or adding at least one additional quiet zone area to the at least one quiet zone area.

An image forming apparatus includes a printing unit, a reversing unit, a writing unit, and a control unit. The printing unit forms an image on a sheet-like medium to which a wireless tag is attached. The reversing unit reverses a front and back of the medium. The writing unit writes data on the wireless tag. The control unit controls the reversing unit so that the medium is reversed twice upon the writing of data on the wireless tag failing and controls the printing unit so that an image indicating that the writing of data fails is formed on the medium reversed twice.

A cryptographically secured voting process that includes applying a blinding process on a voting serial number during registration to hide the vote serial number from a registration authority so there is no way for the registration authority to associate the voting serial number with an identity credential of a voter. The voting process may include applying to a ballot an encrypted voting ticket identifier where the ballot has vote selections, y, and the encrypted voting ticket identifier is s′(x), where, x is a voting ticket id, and function s′( ) is private signer function of an election authority. The voting ticket identifier may be randomly generated. The voting process furthermore including: applying to the ballot an error check hash of the vote selections and the encrypted voting ticket identifier where the error check hash=h(y+s′(x)), where y+s′(x) is a concatenation of y and s′(x).

A method for controlling distribution of a product in a computer network is provided, comprising: providing a computer network having a plurality of processing devices each comprising one or more processors and a storage; and providing keys for asymmetric cryptography in the computer network. In a first data processing device assigned to the manufacturer in the computer network, the following is provided: generating a matrix code by encoding first electronic information comprising the private product key; providing the public product key, the public manufacturer key, and the private manufacturer key; generating a first transaction assigned to the product, a first transaction content of the first transaction comprising the public product key, and the public manufacturer key; and signing the first transaction with both the private product key and the private manufacturer key. Imprint data are provided for imprinting an imprint of the matrix code on the product. Further, a system is provided.

Embodiments described herein provide a computer-implemented method of creating a digest of a document. The document to be processed and analysed may be a physical document, or it may already be in a digital form. In the case of starting from a physical document, the document is first scanned, so as to obtain an image of the document. The digital document is then processed using an algorithm or function to obtain one or more datasets comprising a plurality of position independent values. Each of the datasets may correspond to a different line of text or field of text within the document. The one or more datasets are then encoded, the encoded data being used to generate a digest associated with the document, and wherein the digest comprises a plurality of short hashes corresponding to each dataset. The generated digest can then be used to print a digital signature on the document, which can be used to later verify the authenticity of the document or a copy thereof.

An ink composition contains a semi-drying solvent; a pigment; an alkyd resin; and an amine-based polymeric dispersant. The composition contains 5 wt% or more of the alkyd resin, based on the total weight of the composition, and 5 wt% or more of the amine-based polymeric dispersant, based on the total weight of the composition.

2D machine readable symbologies are stylized and made aesthetically-appealing, facilitating their use to convey plural-symbol data on product packaging and other articles. In some arrangements, symbologies are stylized by geometric transformations (e.g., by multiple rotation and/or mirroring operations) to develop tiles having organized geometric structures. Such stylized symbologies can be decoded by existing code readers. A great variety of other features and arrangements are also detailed.
