  • Patent number: 10540413
    Abstract: A technique allows a newsfeed item shown in a newsfeed of a social network to be easily promoted to another newsfeed in the social network. In a specific embodiment, the system receives a first user's promotion selection of an item displayed in a newsfeed of the first user. The item includes content provided by a second user. The first user is prompted to select a destination newsfeed. A selection of the destination newsfeed is received and the item is published on the destination newsfeed for a third user.

  • Patent number: 10423798
    Abstract: An authenticated print session allows a mobile device to authenticate an encrypted file for printing at a print device sent by a base computer. The base computer authorizes the mobile device to release printing when in close proximity to the print device. The authenticated print session uses the mobile device to authenticate the owner of the encrypted file, and to authorize the release of the file at the print device over a non-secure communication channel.

  • Patent number: 10277608
    Abstract: Whenever users receive or transfer a copy of any of a set of documents, prior verification of the document is enforced by an administrative system, which associates verification metadata with the copy. As each copy is itself copied and transferred, updated verification metadata is included with the previous verification metadata to form a verification lineage chain, which can later be examined to determine the circumstances of any verification failure. Documents are preferably verified by comparing the digital signature of the current copy with the signature of a reference copy. Documents may be signed by submitting them as input records to a distributed, keyless, hash tree infrastructure.

  • Patent number: 10218680
    Abstract: Secure bulk messaging mechanism in which, roughly described, a sender first encrypts a message once. The message can be decrypted with a message decryption key. These can be symmetric or asymmetric keys. For each recipient, the sender then encrypts the message decryption key with the recipient's public key. The sender then sends the encrypted message and the encrypted message decryption keys to a store-and-forward server. Subsequently, one or more recipients connect to the server and retrieve the encrypted message and the message encryption key that has been encrypted with the recipient's public key. Alternatively, the server can forward these items to each individual recipient. The recipient then decrypts the encrypted message decryption key with the recipient's private key, resulting in an un-encrypted message decryption key. The recipient then decrypts the message using the un-encrypted message decryption key.

  • Patent number: 9886588
    Abstract: Proposed is a Capability Management System (CMS) in a distributed computing environment that controls access to multiple objects by multiple subjects based upon a specified access order. A capability is dynamically constructed when the capability is needed. After the capability is used to access an object, a new capability is generated. In the alternative, multiple capabilities for enforcing an access order are generated independently of each other. The new capability is then employed by the same or another subject to access the object according to a prescribed access sequence. In this manner, at any particular time there is one capability valid to access the object by the appropriate subject. In addition, the capability includes information for verifying the authenticity of the capability and for specifying an expiration time associated with the capability. The technology may also be enhanced by providing a linkage between capabilities intended for use in a sequence.

    Abstract: This invention discloses a verifying system and method thereof. The verifying system comprises a plurality of objects to be verified and a verifying end. Each of the objects to be verified respectively comprises an identifying code. The verifying end has a database, and the database stores a plurality records of information of the objects respectively corresponding to each of the indentifying codes. When a user utilizes an electronic device to read one of the indentifying codes for making the electronic device connect to the verifying end, the verifying end compares the identifying code with the plurality records of information of the objects to generate an information of verification results which is then transmitted back to the electronic device. Herewith the effect of the present invention being verifying authenticity of the object by the indentifying code is achieved.

  • Patent number: 8127137
    Abstract: The present invention provides encryption techniques useful with digital watermarking payloads. One claim recites: a method to secure a first digital watermark payload and a second digital watermark payload through encryption of only one of the first digital watermark payload or the second digital watermark payload. The method includes: utilizing a multi-purpose computer processor configured to: provide information redundantly in the first digital watermark payload and the second digital watermark payload, yet the first digital watermark payload includes at least some information that is unique relative to at least the second digital watermark payload; encrypt the first digital watermark payload; embed a first digital watermark in media, the media representing audio, imagery or video, the first digital watermark comprising the encrypted first digital watermark payload; and embed a second digital watermark in the media, the second digital watermark comprising the second digital watermark payload.

  • Patent number: 8117455
    Abstract: A method of authenticating an object in which a computer system receives indicating data from a sensing device. The indicating data is generated in response to sensing of coded data provided on or in a surface associated with the object and is indicative of an identity of the object and at least part of a signature. The signature is in turn a digital signature of at least part of the identity. The computer system uses the indicating to determine a received identity and a received signature part, before using the using the received identity to determine at least a determined signature part. The determined signature part is then compared to the received signature part to authenticate the object.

  • Patent number: 7999973
    Abstract: A method of controlling an apparatus which is capable of determining a dot disposition of a copy-forgery-inhibited pattern image is disclosed. The copy-forgery-inhibited pattern image has a latent image area in which a number of first dots and a number of second dots smaller than the first dots are disposed and a background area in which a number of the second dots are disposed. The first dots can be reproduced when copied. The method includes displaying information related to a disposition of the first dots and the second dots in the latent image area, setting a rate of the first dots that are disposed in the latent image area, or a rate of the second dots that are disposed in the latent image area, in accordance with a designation performed by a user, and determining the dot disposition in the latent image area in accordance with the setting of the rate.

  • Patent number: 7995246
    Abstract: The present invention is concerned with detection of a “fragile watermark” in a printed image to aid in a determination whether a document under examination is an original or a copy. The watermark may be applied by phase-space encoding data to be included in the watermark. The image may be examined on a block-by-block basis after scanning. Correlation of detected watermark strength with block brightness and/or with wave vectors used for encoding may be used to detect that the image is a copy.

  • Patent number: RE44209
    Abstract: A method for secure printing is presented. A document management system (DMS) is provided within a server computer for storing, displaying and printing a plurality of documents. At least a portion of the documents require authentication information for displaying and printing. A web-based capture protection system is provided that prevents proprietary content displayed on a display device from being screen-captured. The web-based capture protection system is combined with the DMS to augment the DMS with capture protection of displayed documents, including intercepting retrieval requests from a client computer to display documents from the DMS.
