Techniques for proving digital photograph authorship using ECG biometrics are described. Electrodes are located on the exterior of a digital camera and are electrically coupled to an ECG circuit. When a photographer holds the camera with both hands, the electrodes detect electrical voltages from the photographer's hands and the ECG circuit produces a digital ECG signal. When the photographer uses the digital camera to capture a photograph, the camera's stenographic engine uses a stenographic key to embedded the ECG signal into the raw image file, producing a watermarked image. The camera's cryptographic engine uses a cryptographic key to encrypt the watermarked image to produce an encrypted image. If a dispute arises regarding authorship of the photograph, the stenographic and cryptographic engines convert the encrypted image into the raw image file and the photographer's ECG signals, which are compared to the ECG signals of the disputed author(s).

Methods and systems are described for receiving and distributing incoming fax transmissions. In one embodiment, an electronic device receives, over a computer network, an electronic message that includes an electronic document and a fax telephone number of an organization of a plurality of organizations, wherein the fax telephone number is) permanently associated with the organization and 2) uniquely identifies the organization from other organizations in the plurality of other organizations. The device determines a destination address of the organization based on the fax telephone number and transmits the electronic document and the fax telephone number to the destination address.

The present invention provides systems and methods for the virtualization, aggregation, and distributed processing of facsimile communications. The Remote FAX Interconnect known as etherFAX® is a system and method that allows for the reception and delivery of information based on cloud computing infrastructure to or from one or more facsimile systems using Internet/web based communication protocols such as HTTP(S) as the transport between a facsimile capable application or hardware and the remotely accessible etherFAX® services.

This application provides a method for transmitting face image data and transferring value, apparatuses, an electronic device, and a storage medium, which belongs to the field of network technologies. The method for transmitting face image data includes acquiring a face data stream through the sensor, and transmitting the face data stream to the first processor; performing image screening on a face image in the face data stream by the first processor to obtain at least a target face image, the target face image meeting a target condition; retrieving a target web address from the memory by the first processor; and transmitting the target face image to the target web address by the first processor.

A device may identify an image to be encrypted, and may convert the image to a first string in a first format. The first string may represent the image. The device may receive information that identifies a key for encrypting the first string, and may generate a first encrypted string by encrypting the first string using the key. The device may convert the first encrypted string, in the first format, to a second encrypted string in a second format. The device may provide the second encrypted string to a storage device without providing the key or the image to the storage device. The storage device may be unable to recover the image using the second encrypted string.

An encryption circuit includes a fundamental vector generation circuit configured to generate a random number sequence for serving as a fundamental vector based on an initial vector, an image mask generation circuit configured to generate an image mask with a mask value set for each pixel in a region to be encrypted smaller than a frame size of the image, based on the fundamental vector and coordinate information for specifying the region to be encrypted, and an XOR operation circuit configured to compute an exclusive OR between each mask value of the image mask and each pixel value of the image data to generate encrypted image data.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells in decipherable. The invention also provide method and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cell for secured viewing on a user browser or computer.

A system and a method for processing an image. The method includes the steps of: receiving a source image having at least one sensitive portions arranged to present intelligible sensitive information; and processing, with a predetermined redacting method, the at least one sensitive portions of the source image to generate an output image including the intelligible sensitive information being transformed into an unintelligible form; wherein the sensitive information in the unintelligible form is adapted to be restored to an intelligible form.

A system includes an image forming apparatus, a first document server apparatus, and a key server apparatus, the image forming apparatus being configured to determine whether document data is private or public, when the document data is determined to be private, then determine a level accessible to the document data, and transmit level information indicating the level and the document data to the first document server apparatus, the first document server apparatus being configured to receive the level information and the document data from the image forming apparatus, generate a document ID for identifying the document data, store the document data in association with the document ID, transmit the document ID to the image forming apparatus, determine an accessible user ID that identifies a user accessible to the document data based on the level information, generate a public key and a private key used to encrypt the document data.

Disclosed are embodiments to manage modifications to a document such that the document conforms to requirements of a label. In some aspects, input assigning a label to a document is received. The label indicates requirements for the document. For example, the label marks the document as confidential, and requires the document to be encrypted when leaving a secure environment. The label may include additional requirements, such as particular watermarking or other content modifications to the document based on the confidential label. A device may be capable of modifying the document such that it satisfies only a subset of the label's requirements. The device then generates a message indicating a gap between the label's requirements and the state of the document, and sends the message to a network service. The network service is configured to augment the document as specified by the additional requirements indicated in the message.
