  • Patent number: 10069868
    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to facilitate multi-factor authentication policy enforcement using one or more policy handlers. An example first policy handler to manage a global policy in a distributed environment includes a parser to identify a first sub-policy of the global policy that is capable of enforcement by the first policy handler, and an attester to sign the first sub-policy. The example first policy handler further includes a director to determine whether to forward the global policy to a second policy handler based on a signature status of the global policy, and to forward the global policy to the second policy handler when the signature status of the global policy is indicative of an unsigned second sub-policy.

  • Patent number: 10033711
    Abstract: Name information which is generated by using a value corresponding to a decryption key and address information of a key cloud device which provides a cloud-key management type decryption service in which the decryption key is used are stored in a storage of a directory service device in a manner to associate the name information with the address information, and a searching unit of the directory service device searches the storage by using the inputted name information to obtain address information corresponding to the inputted name information.

  • Patent number: 10019913
    Abstract: An information encryption system and an information encryption method for encrypting character information and decrypting the encrypted information by using optical character recognition includes a user terminal comprising: a viewer region display unit for displaying a viewer region at the very top of a screen; a viewer character recognition unit for recognizing in real-time characters displayed on a screen region covered by the viewer region, a viewer character encryption unit for generating an encrypted character by encrypting a first character to be encrypted by using a cipher when the first character is recognized; an encrypted character substitution unit for deleting the first character and substitutively inputting the encrypted character; and a viewer character display unit for displaying a non-encrypted second character as it is, and decrypting an encrypted second character by using a cipher and displaying the same in an original character when the second character to be displayed is recognized.

  • Patent number: 9979549
    Abstract: There is provided an information processing apparatus including a key selection section configured to select one out of a plurality of different secret keys, in a public key authentication scheme or a digital signature scheme in which each of the plurality of secret keys exists for one public key registered in a verifier, and a process execution section configured to execute, by using the secret key selected by the key selection section, an authentication process with the verifier by the public key authentication scheme or a digital signature generation process to the verifier by the digital signature scheme.

  • Patent number: 9973520
    Abstract: In an embodiment, the method comprises receiving network performance data for a computer network; receiving, from an intrusion detection system, network anomaly data indicating a plurality of anomalies that have occurred in the computer network; based, at least in part, on the network performance data and the network anomaly data, generating feature data; for each anomaly of the plurality of anomalies, using the feature data to determine a minimal set of features that distinguishes the anomaly from non-anomalies in the plurality of anomalies, and creating a mapping of the anomaly to the minimal set of features; based at least in part on the mapping, generating explanation rules for the plurality of anomalies; for a particular anomaly, identifying a particular rule of the explanation rules that is associated with the particular anomaly, and generating explanation data for the particular anomaly based upon the particular rule.

    Assignee: Cisco Technology, Inc.
    Inventor: Tomas Pevny
  • Patent number: 9948627
    Abstract: The secure electronic document delivery system enables a sender to identify file information and recipient information to be sent to a recipient. The system utilizes an authentication system requiring access to two different authentication messages, both access to electronic mail and access to a message sent to the recipient's phone. The two authentication messages are transmitted via two different communication paths thus requiring the recipient to access two different types of communications. Without accessing both messages, the recipient cannot access the document identified by the sender.
