A method and system for managing the electronic signing of digital documents is disclosed. An electronic document created and prepared for signing by associating certain signing constraints with the document. Indicia of the signing constraints are encoded into a document information block or blocks that are embedded into the document. The information block may include indicia of a database record at a central server that stores indicia of the signing constraints in addition to or in lieu of including the signing constraint indicia in the document information block or blocks. Upon receiving the prepared document at a signing terminal, the information blocks are extracted and the signing constraints tested. If the user desires to sign the document, and if the user is permitted to sign, the document is electronically signed and transmitted to the central file server for storage.

The access method comprises the following steps: i) receiving a notification indicating the presence of at least one digital document available on the network, said notification comprising at least one executable command adapted to detect whether the recipient client device comprises a local application capable of processing the digital document, ii) executing the command or commands in order to detect the local application, and iii) in case of positive detection, accessing the digital document from a local server whereas in case of negative detection, accessing the document from the address of a remote server.

A method of classifying a digital document may include: identifying, by an automated data processor, a request for access to the digital document for a first user; determining user identifying information for the first user; obtaining, by the automated data processor, according to the user identifying information a first user characteristic including organizational affiliation of the first user or a job function of the first user; generating, by the automated data processor, based on the first user characteristic, a digital document classification for the digital document; associating the digital document classification with the digital document, by embedding the document classification in the digital document or logging the document classification in a log identifying the digital document. A user access determination for the digital document may be made according to the associated digital document classification.

A fraud detection system for detecting fraudulent acts related to payment discounts from digital transactional data is disclosed. In some embodiments, the fraud detection system is programmed or configured with data structures and/or database records that are arranged to detect an occurrence of a triggering event, such as receiving an early payment discount by a buyer account from a supplier account. The fraud detection system is programmed to analyze how a first amount charged for certain items by the supplier account to the buyer account before the triggering event has changed to a second amount after the triggering event from digital documents related to procurement transactions. The certain items may include items for sale or for other miscellaneous items. The digital documents may include catalogs, purchase requisitions, purchase orders, or invoices. The fraud detection system is programmed to further detect any potential fraud committed by the supplier account based on the analysis result and assist the buyer account with handling any potential fraud.

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing blockchain-based guarantee information. One of the methods includesreceiving a cyphertext of a digital document specifying a guarantee and one or more zero-knowledge proofs (ZKPs) related to one or more values associated with the guarantee; verifying the one or moreZKPs; upon successfully verifying the one or more ZKPs, storing the cyphertext to a blockchain based on performing a consensus algorithm; receiving a drawdown request of the guarantee from a first computing device associated with the beneficiary or a representative of the beneficiary; storing the drawdown request to the blockchain based on performing a consensus algorithm; and delivering a first message about the drawdown request to a second computing device.

A method for producing a cryptographic timestamp for a digital document using multiple time servers is provided. In the method, a nonce value is produced and a current hash value is formed from the nonce value and the digital document. Then, a time server is repeatedly selected, the current hash value is transmitted to the selected time server, a response comprising a digital signature of the current hash value and a time indication is received by the selected time server, and an additional hash value is determined from the received response and used as the current hash value. The cryptographic timestamp for the digital document is formed from the nonce value and the multiple received responses. The method produces a tamperproof timestamp on a majority basis and is suitable for dating and protocolling in the field of automation and loT.

The invention discloses a distributed document transcoding system. A distributed framework comprises a user uploading interface, a task queue server, two kinds of transcoding server groups (a Linux server group, a Windows server group), and a public server. After a document coded format is classified by the system, a task is pressed in the task queue. According to a priority level, a task server allocates tasks to the transcoding server groups. The transcoding server group keeps monitoring a certain port of the task server and asks for task data according to the own state. After being processed, an intermediate product is transmitted to a next processing procedure and a new task appears and is pressed in the task server message queue, and finally, a picture format of the document is available. The distributed document transcoding system improves the expandability of the system, effectively utilizes the system resources so that different kinds of digital documents are convenient to read online on the internet.

A method of extracting meta-data from semi structured documents, by using area and cone orientation as relevance between words/phrases is described. It also a computer implemented system to handle OCR errors with respect to the coordinates interpreted for each word and user corrections both in online and offline mode. The method is carried out by the steps as follows: converting scanned or digital document to a readable format with coordinates using OCR; scanning the coordinates obtained through OCR for each character; marking all potential labels and values with a bounding box; searching for relevant labels for the particular value by using default control parameters and adjusting trainable parameters; mapping a cone region for the labels and values using the upper and lower angles along x-axis and the scope box and formulating the score area to get the confidence percentage which is used as measure to extract all relevant label-value pairs.

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing blockchain-based guarantee information. One of the methods includesreceiving, by a blockchain node of a first blockchain network, a cross-chain request for relaying a cyphertext of a digital document to a second blockchain network, wherein the cross-chain request issent from a first computing device associated with a guarantor, the digital document specifies a guarantee from the guarantor and one or more predetermined conditions of executing the guarantee; storing the cross-chain request and the cyphertext to a first blockchain associated with the first blockchain network based on performing a consensus algorithm; receiving a message from a second computingdevice for relaying information between the first blockchain network and the second blockchain network, the message includes a confirmation that the guarantee is accepted by the beneficiary and storedon a second blockchain associated with the second blockchain network; and updating a status of the guarantee to indicate that the guarantee has been voided on the first blockchain.
