  • Publication number: 20180025351
    Abstract: Optimizations are provided for completing a transaction event using authentication information. In particular, a presence of a transaction processing device is initially detected. Then, transaction information is received from the transaction processing device. The transaction information corresponds to a current transaction event. After receiving the information, a communication link is established with an on-body device. This device includes authentication information that is necessary to complete the current transaction event. The authentication information is then received from the on-body device. This information has a time-limited use availability. Finally, the received authentication information is used to complete the current transaction event.

  • Patent number: 8146138
    Abstract: A plurality of access units may be established with varying levels of privilege and access rights, such that the user may perform tasks carrying with them a high risk of viral infection in an access unit with a low level of privilege and access rights. When an authenticated user desires to perform tasks requiring a higher level of privilege and access rights, the user may switch to an access unit having a higher privilege and access rights level by instigating a physical action. The physical action may include selecting a button (included in either a UI or on a peripheral device), or inputting biometric data to switch among running access units. A signal instigated by the physical action is transmitted along a trusted path between the isolation kernel and where the physical action was instigated.

  • Publication number: 20120023026
    Abstract: The claimed subject matter provides a system and/or a method that facilitates securing a wireless digital transaction. A terminal component can receive a portion of data related to a payment for at least one of a good or a service. A mobile device can include at least one mobile payment card (m-card), wherein the m-card is created by establishing a link to an account associated with a form of currency. The mobile device can employ public-key cryptography (PKC) to securely and wirelessly transmit a payment to the terminal component utilizing the m-card and linked account.

  • Patent number: 7975117
    Abstract: Plural guest operating systems run on a computer, where a security kernel enforces a policy of isolation among the guest operating systems. An exclusion vector defines a set of pages that cannot be accessed by direct memory access (DMA) devices. The security kernel enforces an isolation policy by causing certain pages to be excluded from direct access. Thus, device drivers in guest operating systems are permitted to control DMA devices directly without virtualization of those devices, while each guest is prevented from using DMA devices to access pages that the guest is not permitted to access under the policy.

  • Patent number: 7957532
    Abstract: A network-based data protection scheme for a mobile device utilizes encryption techniques and a remote key server that stores encryption keys on behalf of the mobile device. The mobile device stores encrypted data, preferably having no unencrypted counterpart stored therewith. On an as-needed basis, the mobile device requests a decryption key (or an encrypted version of a decryption key) from the key server, where the decryption key can be used by the mobile device to decrypt the encrypted information. The key server transmits the decryption key to the mobile device after authenticating the user of the mobile device.

  • Patent number: 7900837
    Abstract: Techniques for authenticating certificates of authenticity (COAs) are discussed. The techniques provide for a simplified authentication system that is easily utilized in a field setting. In described embodiments, COAs are attached to or otherwise associated with goods to be authenticated. The COAs incorporate random or pseudo-random arrangements of optically sensitive fibers to create unique identifiers. A COA reader device optically scans each COA and characterizes the COA according to its unique arrangement of optical activity. A COA reader device may also scan data (e.g., a barcode) that is associated with the COA. The data contains information about the COA to further strengthen the COA authentication process. Based on the scan, the goods associated with the COAs can be verified as genuine (i.e., not pirated).

  • Patent number: 7878398
    Abstract: Techniques are disclosed to enable utilization of randomly-occurring features of a label (whether embedded or naturally inherent) to provide counterfeit-resistant and/or tamper-resistant labels. More specifically, labels including randomly-occurring features are scanned to determine the labels' features. The information from the scan is utilized to provide identifying indicia which uniquely identifies each label and may be later verified against the label features that are present to determine whether the label is genuine. In a described implementation, the identifying indicia may be cryptographically signed.

  • Patent number: 7818799
    Abstract: A tamper response mechanism introduces a delayed failure into a program in response to detected tampering with the program. The mechanism determines a manner of responding to the detected tampering. The manner of responding may include corrupting a global pointer or using other techniques. The mechanism also determines when to respond to the tampering and implements the response at the determined time.
