A secure content object protects electronic documents from unauthorized use. The secure content object includes an encrypted electronic document, a multi-key encryption table having at least one multi-key component, an encrypted header and a user interface device. The encrypted document is encrypted using a document encryption key associated with a multi-key encryption method. The encrypted header includes an encryption marker formed by a random number followed by a derivable variation of the same random number. The user interface device enables a user to input a user authorization. The user authorization is combined with each of the multi-key components in the multi-key encryption key table and used to try to decrypt the encrypted header. If the encryption marker is successfully decrypted, the electronic document may be decrypted. Multiple electronic documents or a document and annotations may be protected by the secure content object.

For example, an implementation of the present invention can comprise a method for authenticating a user. The method can comprise an authentication server receiving from a user a password. The server can then hash the password such that a password hash is created. The server can then receive a second token from the user. Using the second token, the server can identify a sequence of characters associated with the second token within the password hash. The server can create an authentication token by removing the sequence of characters from the password hash. If the authentication token matches a stored value, the server can authenticate the user.

A PIN is automatically generated based on at least one rule when the user enters a password through a user device. In one example, the PIN is a truncated version of the password where each character in the truncated version is mapped onto a number. The mapping can be a truncation at the beginning or end of the password, or the mapping can be with any pattern or sequence of characters in the password. This PIN generation may be transparent to the user, such that the user may not even know the PIN was generated when the password was entered. When the user attempts to access restricted content, the user may enter the PIN instead of the password, where the user may be notified of the rule used to generate the PIN so that the user will know the PIN by knowing the password.

A system for passively analyzing an aggregation of communication signals simultaneously passing through a network link performs spectral analysis on a trace of communication traffic through the network link. The spectral analysis identifies period components of the trace corresponding to different communication signals. A system for deterring the passive analysis of signals aggregates communication traffic through a network link, such that a plurality of signals simultaneously pass through the network link. The plurality of signals is regulated such that the data packets corresponding to the plurality of signals leave the network link at a common rate. A memory temporarily stores the data packets as they enter the network link, and a timer maintains a fixed time interval for releasing the data packets from the memory.

The puzzle may have multiple cylinders with multiple pin / groove pairs, may have different pin / maze arrangements, may be constructed of plastic, wood, or other material, may include secret compartments, may vary in diameter and skill level to suit users of differing mental and physical abilities, and may have interchangeable components to minimize obsolescence from user fluency.

When a fee setting server acquires end-of-utilization information from a vehicle, the fee setting server requests the vehicle to shoot an image serving as in-vehicle image data (information of the number of occupants). When the fee setting server acquires the in-vehicle image data from the vehicle, the fee setting server specifies the number of riding occupants from the acquired in-vehicle image data, and sets the number of occupants. In a case where the set number of occupants is large, the fee setting server sets a utilization fee for car sharing to be lower than that in a case where the number of occupants is small.
