Phishing attacks succeed by exploiting a user's inability to distinguish legitimate websites from spoofed websites. Most prior work focuses on assisting the user in making this distinction; however, users must make the right security decision every time. Unfortunately, humans are ill-suited for performing the security checks necessary for secure site identification, and a single mistake may result in a total compromise of the user's online account. Fundamentally, users should be authenticated using information that they cannot readily reveal to malicious parties. Placing less reliance on the user during the authentication process enhances security and eliminates many forms of fraud.

US08352727B2 Protection of data delivered out-of-order
A basic idea of this system is to separate ordered delivery data and unordered delivery data in a security protocol running on top of a reliable transport protocol, and perform a first type of security processing for ordered delivery data and a second different type of security processing for unordered delivery data in the security protocol. Preferably, data messages using ordered delivery and data messages using unordered delivery within a secure data stream are separated into two message sequence spaces on the security protocol layer, and data security processing is then performed differently in these two spaces. This system is particularly suitable for a reliable transport protocol such as SCTP (Stream Control Transmission Protocol). The security protocol running on top of the transport protocol is preferably based on the TLS (Transport Layer Security) or a TLS-like protocol with a security processing extension for unordered delivery.
US08352725B1 Method and apparatus for managing secure communications
A device for managing secure communications by examining message packets to detect and control the use of encryption keys noninvasively examines an incoming message packet according to typical cryptographic protocols and sequences. If an incoming packet exhibits the use of an encryption key, such as via IKEP, IPsec, or PPTP, the device processes the packet to attempt to find the corresponding encryption key. The device compares the key to a list of known suspect keys to determine a blocked status. If the key is not on the list, a sequence of authorization rules concerning prohibited key usage attempts to determine a result. The authorization rules examine available keying attributes from the message packet, possibly via a remote server, and compute an indication concerning key usage. If the authorization rules are still undeterministic of usage of the key, the device uses a default action. The default action indicates whether to allow or block usage of the key until a deterministic response indicates the key status.

US08352257B2 Spectro-temporal varying approach for speech enhancement
The present system proposes a technique called the spectro-temporal varying technique, to compute the suppression gain. This method is motivated by the perceptual properties of human auditory system; specifically, that the human ear has higher frequency resolution in the lower frequencies band and less frequency resolution in the higher frequencies, and also that the important speech information in the high frequencies are consonants which usually have random noise spectral shape. A second property of the human auditory system is that the human ear has lower temporal resolution in the lower frequencies and higher temporal resolution in the higher frequencies. Based on that, the system uses a spectro-temporal varying method which introduces the concept of frequency-smoothing by modifying the estimation of the a posteriori SNR. In addition, the system also makes the a priori SNR time-smoothing factor depend on frequency. As a result, the present method has better performance in reducing the amount of musical noise and preserves the naturalness of speech especially in very noisy conditions than do conventional methods.

US08352194B1 Method to identify cancer fusion genes
Numerous cancer fusion genes have been identified and studied, and in some cases therapy or diagnostic techniques have been designed that are specific to the fusion protein encoded by the fusion gene. However, there has been little progress in understanding the general features of cancer fusions genes in a way that could provide the foundation for an algorithm for predicting the occurrence of a fusion gene once the chromosomal translocation points have been identified by karyotype analyses.

These results support a basis for designing algorithms that could have a high degree of predictive value in identifying fusion genes once conventional microscopic analyses have identified the chromosomal breakpoints.
