Abstract: Methods and apparatus to certify digital signatures are disclosed. An example method includes retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in a request to certify a digital signature, comparing the first geographical location associated with the identification number to a second geographical location to verify the second geographical location, and in response to the verification of the second geographical location and to a comparison of (a) biometric information associated with a user associated with the request and (b) stored biometric information, instructing a certificate issuer to certify the digital signature to indicate an authenticity of the digital signature.

Abstract: A disclosed method of authenticating a telephone caller includes receiving an authentication request for the telephone caller that includes a voice recording of the caller and household information indicative of a household, creating a first voice pattern based on the voice recording of the caller, retrieving a second voice pattern using at least some of the household information, comparing the two voice patterns, and transmitting information indicative of the results of the comparison. The transmitted information may include information that the telephone caller is authenticated, is not authenticated, or that the comparison results were inconclusive. The method may include monitoring telephone calls with the household, and if it is determined that a voice on at least some of the telephone calls is associated with the household, creating the second voice pattern based on the voice, and associating the second voice pattern to the household.

An example method includes retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in a request to certify a digital signature, comparing the first geographical location associated with the identification number to a second geographical location to verify the second geographical location, determining that the first geographical location matches the second geographical location, and certifying the digital signature to indicate an authenticity of the digital signature based on the verification of the second geographical location and a comparison of (a) biometric information associated with a user associated with the request and (b) stored biometric information.

Abstract: A method for accessing a remote network includes identifying a content server associated with the remote network, generating a uniform resource locator, embedding additional data in the uniform resource locator, encrypting the uniform resource locator, and accessing a server in the remote network identified by the uniform resource locator. The method further includes wherein the additional data comprises authentication data, a delivery session identification, a time stamp, or comprises subscriber identification data. The URL may provide access to the content server for a time period indicated by the time stamp. The method includes wherein at least the subscriber identification data prevents unauthorized sharing of the URL.

Abstract: Methods and apparatus to certify digital signatures are disclosed. An example method includes receiving a request to certify a digital signature from a user, receiving information about a physical characteristic of the user, comparing the information about the physical characteristic to stored physical characteristic information, and based on the comparison, at least one of certifying the digital signature based on the comparison or requesting certification of the digital signature based on the comparison.

Abstract: A particular method includes receiving, via an interactive voice response unit, an audio content item during a first call. An indication of an insertion point at which to insert audio advertising in the audio content item is also received. The method further includes receiving via the interactive voice response unit an audio advertisement during a second call. The audio advertisement is automatically inserted into the audio content item at the insertion point to create a package.

Abstract: An audio content item, submitted by and spoken in a voice of an author, is received and registered along with an insertion point and associated content information. An audio advertisement submitted by an advertiser is received and registered. At least one targeting criterion is associated with the audio advertisement. User information and at least one content pushing criterion are stored for a user. Without being selected by the user, the audio content item is automatically selected for pushing to the user based on the content information satisfying the at least one content pushing criterion. The audio advertisement is automatically selected for insertion at the insertion point based on the content information and the user information satisfying the at least one targeting criteria. A package that includes the audio content item with the audio advertisement inserted at the insertion point is created and pushed to the user.

Abstract: Program identifiers from an electronic programming guide are added to a wish list. The wish list may be created automatically from user preferences or from manual user selections. In some embodiments, the wish list is available from different platforms including set-top boxes, personal computers, and mobile telephones. Users are not required to scroll through an entire list of available on-demand movie titles, for example, to choose those that may later be selected for viewing. Instead, a user may scroll through an entire list once and move any items of interest to a wish list for later consideration.

Abstract: A method is disclosed for quickly and easily determining the presence and concentration of aflatoxins in peanuts. Aflatoxins are extracted from ground peanuts with a methanol-water solution using a tissuemizer. The extracted sample is filtered and an aliquot of the filtrate is transferred to a separatory funnel. A salt solution is added to remove interferences. The combined aqueous solution is then extracted with dichloromethane. The dichloromethane extract is evaporated to dryness, trifluoroacetic acid is then added and the resulting residue taken up in the mobile phase. The solution is then passed through a minicolumn for filtration and final cleanup. An aliquot is then injected into a high pressure liquid chromatograph system for separation of the four aflatoxin components, B1, B2, G1 and G2. Quantitation is done using a filter fluorescence detector.
