Systems and methods for smartkey information management

1. A smartkey-based computer file access system, said system including:

a user computer system operating a smartkey encryption/decryption application, wherein said smartkey encryption/decryption application receives:

a smartkey team name data for a team;

a first user password data; wherein said first user is a member of said team

a second user password data; wherein said second user is a member of said team

a team public key data; and

a team private key data,

wherein said smartkey encryption/decryption application forms a smartkey electronic data structure including:

said smartkey team name data in unencrypted form;

a team encrypted master key data, wherein said team encrypted master key data is formed by said smartkey encryption/decryption application by determining a master key data derived from random data and encrypting said master key using said team public key data;

a first user password-accessible team encrypted master key data comprising:

said team public key data; and

said team private key data, encrypted by said first user password to form a first user encrypted team key data; and

a second user password-accessible team encrypted master key data comprising:

said team public key data; and

said team private key data, encrypted by said second user password to form a second user encrypted team key data,

wherein said smartkey encryption/decryption application receives an electronic data file,

wherein said smartkey encryption/decryption application forms a session key associated with said electronic data file and encrypts said data file to form an encrypted data file using said session key,

wherein said smartkey encryption/decryption application encrypts said session key using said team encrypted master key data and stores the result as a team encrypted session key data in said smartkey electronic data structure; and

a smartkey provider computer system, wherein said smartkey encryption/decryption application initiates the transmission of said smartkey electronic data structure from said user computer system to said smartkey computer provider system,

wherein said smartkey electronic data structure is stored at said smartkey computer provider system and a second user computer system operating an instance of said smartkey encryption/decryption application, wherein said second user computer system receives:

a target smartkey team name data;

said encrypted data file; and

a user password data representing a user to be allowed to decrypt said encrypted data file, wherein said user is a member of said team,

wherein said second computer system transmits said target smartkey team name data to said smartkey provider system,

wherein said smartkey provider system searches a plurality of stored smartkey electronic data structures, identifies a smartkey electronic data structure including smartkey team name data matching said target smartkey team name data, and transmits said smartkey data structure to said second computer system,

wherein said second computer system uses said user password data to decrypt said user password-accessible encrypted team key data to obtain said team private key data,

wherein said second computer system uses said team private key data to decrypt said team encrypted master key data to obtain said master key data,

wherein said second computer system uses said master key data to decrypt said team encrypted session key data to obtain said session key data, and

wherein said second computer system uses said session data to decrypt said encrypted data.

2. The system of claim 1 wherein a plurality of data files are encrypted using a plurality of different session keys and said plurality of different session keys are stored in the smartkey electronic data structure.

3. The system of claim 2 wherein the smartkey electronic data structure stores said plurality of session keys in a plurality of session key locations inside said smartkey electronic data structure, wherein each session key location is associated with a specific one of said plurality of data files.
