Embodiments of the present disclosure provide an information processing method, an electronic device and a computer storage medium, the electronic device obtains, by the sensor unit, at least one trigger operation; detects whether the at least one trigger operation meets a preset encryption condition to acquire a detection result; determines target file data according to preset rules when the detection result is the at least one trigger operation meets the preset encryption conditions; and encrypts the target file data.

Digital media can be automatically transferred between a digital capture device or storage device and one or more other devices with little or no user intervention. Media can be selected for automatic transfer based on one or more media-content or media-context characteristics.

An encoding unit encodes at least a part of items of a CSV file including a plurality of records having a plurality of items with a unit of items of respective records. A creation unit creates an encrypted dictionary in which an encoded dictionary having been used for the encoding is encrypted with a unit of dictionary. A transmission unit sends, according to a request for a part of records included in the data, encoded data including the encoded part of records and the encrypted dictionary to a requesting source. A requesting unit requests a part of records included in the CSV file. A decryption unit decrypts the encoded data received according to the request by using the encrypted dictionary.

A license management server is connected with a plurality of image forming apparatuses. The server includes a memory that stores a limited license for enabling a restricted function of the image forming apparatuses, and a processor configured to determine whether the license can be issued to one of the image forming apparatuses, and upon determining that the license can be issued to the one of the image forming apparatuses, transmit the license enabling the restricted function to the one of the image forming apparatuses.

A printing apparatus includes: a printing apparatus storage unit that stores firmware to which a public key is added, the public key being information related to a public key encryption method; a printing apparatus network-communication unit that receives signature information obtained by encrypting a hash value of overwriting firmware with a private key corresponding to the public key, from the management server, and that receives the overwriting firmware from the file providing server; and a printing apparatus control unit that determines validity of the overwriting firmware by comparing a hash value generated by decrypting the signature information which is received from the management server with the public key stored in the printing apparatus storage unit, and a hash value of the overwriting firmware which is received from the file providing server.

A method for watermarking a document containing at least one text portion comprising the following steps: determining a specific character font comprising, for at least one character, an original graphic and at least one variation, each of the variations being associated with a different value, said character being termed encodable characters; using the specific character font to encode an item of information in the text portion of the document, by replacing at least one original graphic with a variation, the original graphic and the variation or variations being identified as a single character by a first optical character recognition process referred to as standard OCR and identified as a plurality of characters by a second optical character recognition process referred to as specific OCR that is capable of determining if the represented character is the original graphic or one of the variations of same and, if so, making it possible to determine the variation that is represented, a strict order relationship being defined on the encodable characters in order to establish the order in which the encodable characters are to be processed during the decoding phase.

A document printing system may include a print engine, a controller and a communication port. The communication port can read a portable memory device, which stores an electronic secure file for authorizing the print engine. The portable memory device may store data such as the creation date for the electronic secure file. The portable memory may also store the device identification code and/or the vendor identification code. The electronic secure file may also store the creation date for the file itself, and the device identification code, the vendor identification code, or a balance amount. The system may authorize a print engine by comparing the data in the electronic secure file and data stored on the portable memory device. If the comparison of data finds a mismatch, the system may determine that the print engine is not authorized; or that the service is authorized if otherwise.

A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processor also places the augmented captured information in association with subscriber information in a transmission of the augmented captured information to a receiving facility requiring such subscriber information. A transmitter transmits the transmission including the augmented captured information and the subscriber information to the receiving facility. An encryptor encrypts the augmented captured information with a symmetrical encryption algorithm to provide encrypted augmented captured information in the transmission with the subscriber information.

The system may authorize a print engine by comparing the data in the electronic secure file and data stored on the portable memory device. If the comparison of data finds a mismatch, the system may determine that the print engine is not authorized; or determine that the service is authorized if otherwise.

An encrypted file printing system includes: a client terminal configured to generate a print file; an authorization management server configured to manage authorization of the print file; and an image forming apparatus configured to perform printing of the print file, the client terminal, the authorization management server, and the image forming apparatus being connected by a communication network, wherein the authorization management server includes: a key generating unit; and a decrypting unit, the client terminal includes: an encrypting unit; and a print instructing unit, the image forming apparatus includes: a decrypting unit; a rasterizing unit; a memory; and a control unit, and the control unit includes: a complexity calculating unit; a processing time calculating unit configured to calculate a first processing time in a first processing mode and a second processing time in a second processing mode; and a decryption destination determining unit.
