FIELD OF THE INVENTION
The present invention is related to a trusted and decentralized peer-to-peer network method and system.
BACKGROUND OF THE INVENTION
Important to the business of selling movies electronically via the Internet includes efficient electronic distribution and/or file sharing. The process of sharing computer files (including digitized movies) via communications means has increased in importance with the proliferation of the Internet for electronic distribution and file transfer. The creation of file sharing and/or peer-to-peer networks (e.g. Gnutella) has enabled users of computer workstations, which lack traditional serving software to distribute computer files. Traditionally, serving computers (e.g. computers running Microsoft Windows 2000 Server) performed the task of distributing computer files to client work stations using a centralized network architecture. The advent of file sharing and/or peer-to-peer networks gave way to a decentralized network architecture comprised of multiple computer workstations (e.g. host nodes) acting as redundant repositories, each capable of transferring the same computer files. Some of the current file sharing and/or peer-to-peer networks communicate in an open and un-trusted manner. Additionally, trusted peer-to-peer networks have relied on a centralized process of identifying members and their related IP address to establish the trusted peer-to-peer network.
SUMMARY OF THE INVENTION
The present invention offers a new and improved method and system to establish a trusted and decentralized peer-to-peer network for: the sharing of computer files between and among computing devices; trusted chat sessions; and for other applications of trusted peer-to-peer networks. Additionally, the present invention also offers a new and improved method and system to provide file identification properties or attributes prior to the actual download of the file through file sharing utilizing a trusted and decentralized peer-to-peer network. The present invention can be a software program residing computing devices permitting users to automatically interact in a trusted peer-to-peer manner during the file sharing process.

Next the Setup.exe File 41 creates the FindMe Folder 60, the Searched FindMe Results Folder 61, and the Trusted Search Folder 62 on the Storage 23. These steps are performed for each computing device (e.g. Device “A” 10, Device “B” 11, Device “C” 12, Device “D” 13) intended to run the Peer-to-Peer Network Program 40.
Next, and upon first use of the Peer-to-Peer Network Program 40, the Peer-to-Peer Network Program 40 prompts the user of the host computing device to input a name which identifies that user (e.g. UserA). Next, the Peer-to-Peer Network Program 40 calls cryptographic functionality of the CryptoAPI 70 (e.g. the Peer-to-Peer Network Program 40 calls the “CryptAcquireContext” function of the Windows CryptoAPI) of the Operating System 25 to create a public/private key pair. Next, the CryptoAPI 70 returns a handle to the Cryptographic Service Provider 71 (e.g. the Windows CryptoAPI returns a handle to the Microsoft RSA/Schannel Cryptographic Service Provider to the Peer-to-Peer Network Program 40). Next, the Peer-to-Peer Network Program 40 calls cryptographic functionality of the CryptoAPI 70 of the Operating System 25 to instruct the Cryptographic Service Provider 71 to execute the creation of the public/private key pair (e.g. the Peer-to-Peer Network Program 40 calls the “CryptGenKey” function of the Windows CryptoAPI). Next, the CryptoAPI 70 instructs the Cryptographic Service Provider 71 (e.g. the Windows CryptoAPI instructs the Microsoft RSA/Schannel Cryptographic Service Provider to create the public/private key pair (e.g. UserAPublic Key 80 and UserA Private Key 90)).
Next, the Peer-to-Peer Network Program 40 creates a plaintext version of the UserA FindMe File 100 (e.g. a text file), and at this point UserA FindMe File 100 is a blank file. Next, the Peer-to-Peer Network Program 40 calls functionality of the Application Programming Interface 72 of the Operating System 25 and obtains identifiable network information on the host computing device (e.g. Device “A” 10) (e.g. the Peer-to-Peer Network Program 40 calls the “CurrentIpAddress” function of the Windows API). Next, the Application Programming Interface 72 queries the Operating System 25 and obtains identifiable network information on the host computing device (e.g. Device “A” 10), then the Application Programming Interface 72 transmits the identifiable network information to the Peer-to-Peer Network Program 40. Next, the Peer-to-Peer Network Program 40 writes the identifiable network information into the plaintext version of the UserA FindMe File 100. Next, the Peer-to-Peer Network Program 40 calls cryptographic functionality of the CryptoAPI 70 (e.g. the Peer-to-Peer Network Program 40 calls the “CPEncrypt” function of the Windows CryptoAPI) of the Operating System 25 to encrypt the UserA FindMe File 100 with a private key (e.g. the UserA Private Key 90). At this point the Peer-to-Peer Network Program 40 is configured to execute other embodiments of the invention.
Next, and each time, the user initiates the Peer-to-Peer Network Program 40 by means of the User Interface 20, the Peer-to-Peer Network Program 40 automatically searches each of the Trusted Search Folders 62 for computer files lacking a File Info Stream 120 through use of functionality of the Application Programming Interface 72 of the Operating System 25 (e.g. the Peer-to-Peer Network Program 40 calls the “FileSystemObject” object model of the Windows API to open, write, create, and test computer files). Next, and for each computer file in each of the Trusted Search Folders 62 that lacks a File Info Stream 120, the Peer-to-Peer Network Program 40 calls functionality of the Application Programming Interface 72 of the Operating System 25, then opens the User Information File 50, then writes information from the User Information File 50 into the File Info Stream 120 (e.g. the Peer-to-Peer Network Program 40 calls the “FileSystemObject” object model of the Windows API to open, write, create, and test computer files). The Peer-to-Peer Network Program 40 also enables the user of the host computing device to manually input other information into the File Info Stream 120 for each related computer file and accomplishes this task by calling functionality of the Application Programming Interface 72 of the Operating System 25, then writes the information the user manually inputted into the File Info Stream 120 (e.g. the Peer-to-Peer Network Program 40 calls the “FileSystemObject” object model of the Windows API to open, write, create, and test computer files).
Next, the user (e.g. UserA) of a computing device (e.g. Device “A” 10) inputs a command to the Peer-to-Peer Network Program 40 via the User Interface 20, to export their related public key (e.g. UserA Public Key 80) to a recipient or recipients, being a user of a another computing device or to other users of other computing devices and the UserA inputs the E-mail addresses of the recipient or recipients. Next, the Peer-to-Peer Network Program 40 calls functionality of the CryptoAPI 70 of the Operating System 25 to create a computer file capable of transporting the UserA Public Key 80 (e.g. the Peer-to-Peer Network Program 40 calls the “CryptExportKey” function of the Windows CryptoAPI to generate a public key BLOB of UserA Public Key 110). Next, the Peer-to-Peer Network Program 40 instructs the E-mail Program 130 of the Device “A” 10 to transmit to the recipient or recipients the name of the UserA FindMe File 110 and a copy of the UserA Public Key BLOB 110. Next, the E-mail Program 130 of a recipient's computing device (e.g. Device “B” 11) receives from transmission from the UserA the name of the UserA FindMe File 110 and a copy of the UserA Public Key BLOB 110.
Next, the user of the Device “B” 11 (upon receipt of E-mail transmission from the UserA the name of the UserA FindMe File 110 and the copy of the UserA Public Key BLOB 110) instructs the Peer-to-Peer Network Program 40 via the User Interface 20, to import the UserA Public Key 80. Next, the Peer-to-Peer Network Program 40 instructs the CryptoAPI 70 of the Operating System 25 of the Device “B” 11 to import the UserA Public Key 80 from the UserA Public Key BLOB 110 to the Cryptographic Service Provider 71 (e.g. the Peer-to-Peer Network Program 40 calls the “CryptImportKey” function of the Windows CryptoAPI, then the Windows CryptoAPI extracts the UserA Public Key 80 from the UserA Public Key BLOB 110, then the Windows CryptoAPI imports and the UserA Public Key 80 to the Microsoft RSA/Schannel Cryptographic Service Provider). Next the Peer-to-Peer Network Program 40 writes an entry in the Trusted Member List 140 establishing (or maping) a relationship between the name of the UserA FindMe File 100 (as received from E-mail transmission) and the UserA Public Key 80.
Next, the user of the Device “A” 10 (e.g. UserA) instructs the Peer-to-Peer Network Program 40 via the User Interface 20 of Device “A” 10, to search (via the Communications Means 30) for members (who are then connected to the Communications Means 30) listed in the Trusted Member List 140 (being the members of the trusted peer-to-peer network the Peer-to-Peer Network Program 40 is capable of establishing) via connected to the Communications Means 30. Next, the Peer-to-Peer Network Program 40 accesses the list of computer file names in the Trusted Member List 140 and executes a search request of an un-trusted peer-to-peer network for computer files matching the name of the computer files listed in the Trusted Member List 140 utilizing the File Sharing Protocols 153. Next, the Peer-to-Peer Network Program 40 of another computing device (e.g. Device “B” 11) receives the search request for various computer files (e.g. user “FindMe” files) and transmits the computer files matching the search request (e.g. UserB FindMe File 101) to the Device “A” 10 utilizing transmission protocols (e.g. FTP Protocol 150, HTTP Protocol 151).
Next, the Peer-to-Peer Network Program 40 of the Device “A” 10 receives from transmission the UserB FindMe File 101, then saves the UserB FindMe File 101 in the FindMe Results Folder 61 in Storage 23 of the Device “A” 10. Next, the Peer-to-Peer Network Program 40 instructs the CryptoAPI 70 of the Operating System 25 of the Device “A” 10 to decrypt the UserA FindMe File 101 using the public key as associated with the UserA FindMe File 101 in the Trusted Member List 140 through use of the Cryptographic Service Provider 71 (e.g. the Peer-to-Peer Network Program 40 calls the “CPDecrypt” function of the Windows CryptoAPI, then the Windows CryptoAPI calls the UserB Public Key 81 from the Microsoft RSA/Schannel Cryptographic Service Provider, then the Windows CryptoAPI decrypts the UserB FindMe File 101 creating a plaintext version of the UserB FindMe File 101). Next, the Peer-to-Peer Network Program 40 of the Device “A” 10 opens the plaintext version of the UserB FindMe File 101) and reads the identifiable network information (e.g. the IP address of Device “B” 11) then writes an entry in the Trusted Member List 140 containing: the identifiable network information of Device “B” 11, the name of the UserB FindMe File 101, and name of the UserB. At this point, the user of the Device “A” 10 is able to use the Peer-to-Peer Network Program 40 to establish a trusted and decentralized peer-to-peer network, utilizing the IP addresses listed on a member-by-member basis in the Trusted Member List 140.
Users of the Peer-to-Peer Network Program 40 can utilize the trusted and decentralized peer-to-peer network to establish trusted chat sessions. This is accomplished when the user of a computing device (e.g. Device “A” 10) instructs the Peer-to-Peer Network Program 40 via the User Interface 20, to establish a chat session with user defined members listed in the Trusted Member List 140. Next, the Peer-to-Peer Network Program 40 reads the identifiable network information (e.g. the IP address of the members) in the Trusted Member List 140 of the members, then, using the Chat Protocol 152, the Peer-to-Peer Network Program 40 transmits a chat session request to the computing devices (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) of the members (e.g. UserB, UserC, UserD, etc.). Each computing device that is then: connected to the Communications Means 30 utilizing identifiable network information (e.g. IP address) matching the identifiable network information listed on a member-by-member basis in the Trusted Member List 140 of the Device “A” 10; running the Peer-to-Peer Network Program 40; and receives the transmitted chat session request from Device “A” 10 utilizing the Chat Protocol 152; then notifies the user (e.g. UserB, UserC, UserD, etc.) of that particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) via the User Interface 20 of their respective computing device, that a chat session has been initiated by a member of the trusted network. Next, the user (e.g. UserB, UserC, UserD, etc.) of that particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) instructs the Peer-to-Peer Network Program 40 to either accept or deny the chat session, via the User Interface 20 of their respective computing device. If the user (e.g. UserB, UserC, UserD, etc.) of that particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) instructs the Peer-to-Peer Network Program 40 to deny the chat session, via the User Interface 20 of their respective computing device, then the Peer-to-Peer Network Program 40 denies the chat session utilizing the Chat Protocol 152 and transmits a denial notification to the Peer-to-Peer Network Program 40 of the Device “A” 10, then the Peer-to-Peer Network Program 40 of the Device “A” 10 notifies the user (e.g. UserA) of the Device “A” 10 that the chat session has been denied, then the Peer-to-Peer Network Program 40 of the Device “B” 11 ends the chat session utilizing the Chat Protocol 152. If the user (e.g. UserB, UserC, UserD, etc.) of that particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) instructs the Peer-to-Peer Network Program 40 to accept the chat session, via the User Interface 20 of their respective computing device, then the Peer-to-Peer Network Program 40 accepts the chat session utilizing the Chat Protocol 152, then the Peer-to-Peer Network Program 40 maintains the chat session utilizing the Chat Protocol 152.
Users of the Peer-to-Peer Network Program 40 can utilize the trusted and decentralized peer-to-peer network to conduct trusted file sharing or searching. This is accomplished when the user of a computing device (e.g. Device “A” 10) instructs the Peer-to-Peer Network Program 40 via the User Interface 20, to establish a file search of the computing devices controlled or operated by the members listed in the Trusted Member List 140 by inputting the name of the computer file desired via the User Interface 20. Next, the Peer-to-Peer Network Program 40 reads the identifiable network information (e.g. the IP address of the members) in the Trusted Member List 140 of the members, then, using the File Sharing Protocols 153, the Peer-to-Peer Network Program 40 transmits a search request, for the computer file requested by UserA, to the computing devices listed in the Trusted Member List 140 (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) of the members (e.g. UserB, UserC, UserD, etc.). Each computing device that is then: connected to the Communications Means 30 utilizing identifiable network information (e.g. IP address) matching the identifiable network information listed on a member-by-member basis in the Trusted Member List 140 of the Device “A” 10; running the Peer-to-Peer Network Program 40; and receives the transmitted file search request from Device “A” 10 utilizing the File Sharing Protocols 153; then the Peer-to-Peer Network Program 40 of that particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) searches for the requested file in the Trusted Search Folder 62.
If the requested computer file is not located by the Peer-to-Peer Network Program 40 of a particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) in the respective Trusted Search Folder 62, then the Peer-to-Peer Network Program 40 does not reply. If the requested computer file is located by the Peer-to-Peer Network Program 40 of a particular computing device (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) in the respective Trusted Search Folder 62, then the Peer-to-Peer Network Program 40 transmits the name of the matching computer file along with any information found in the File Info Stream 120 related to the matching computer file, to the Peer-to-Peer Network Program 40 of the Device “A” 10. Next, the Peer-to-Peer Network Program 40 of the Device “A” 10 displays via the User Interface 20, the computer file names, and any information found in the File Info Stream 120 related to the matching computer file, received from any and/or all computing devices (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.) that have responded to the search request. Next, the user of the Device “A” 10 selects, via the User Interface 20, which computer file or computer files the Peer-to-Peer Network Program 40 is to download via the trusted peer-to-peer network. Next, the Peer-to-Peer Network Program 40 of the Device “A” 10 transmits a download request using communication protocols (e.g. FTP Protocol 150, HTTP Protocol 151) to the computing device and/or computing devices, by means of the identifiable network information (e.g. the IP address of the computing device and/or computing devices) in the Trusted Member List 140 and as associated with the specific computer file or computer files selected by the UserA. Next, the Peer-to-Peer Network Program 40 of the computing device and/or computing devices respectively (e.g. Device “B” 11, Device “C” 12, Device “D” 13, etc.), containing the computer file or computer files selected by the UserA, initiates a download of the computer file or computer files using communication protocols (e.g. FTP Protocol 150, HTTP Protocol 151). Next, the Peer-to-Peer Network Program 40 of the Device “A” 10 receives and saves the download computer file or computer files to the Trusted Search Folder 62.
Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
