A system and method for extended access to a plurality of Internet resources from an Internet access terminal.

Since the generalization of the Internet, it has appeared desirable to guarantee Internet users a high level of quality of Internet resources by ensuring their availability at all times and by guaranteeing their security by distributing resources over a large number of points of the network. , by duplicating services on a large number of network points and by the use of encryption techniques.

One of the aims of the invention is to propose a system and a method of access between an Internet access terminal and a plurality of remote Internet resources that can meet these objectives, allowing adaptation to specific cases. very varied, as will be explained later, but while maintaining excellent security and excellent control of access to the Internet resource.

The invention consists mainly of an Internet access agent server (13, 13.1 and 13.2) delivered to the user and which the user inserts between his access terminal and a local device for connecting to the Internet. .

The Internet terminal may be a microcomputer (16) equipped. appropriate Internet browser software and a microphone + headset audio handset, a dedicated Internet access device connected to a television, household appliance or radio communication device. Such a configuration is however not limiting and may include various GSM phone variants with an Internet access system, refrigerator with its own display for Internet access, drinks vending machine with an integrated Internet access system. In addition, the term Internet should be considered equivalent to the term network interconnection and data transport The device for connecting to the Internet may be a modem (24.1) or a router (24.2).

Such a configuration is however not limiting and may include various variants: satellite receiver, wireless local loop receiver, integrated modem of a GSM telephone (27), local loop reception antenna, gateway, switch.

The Internet access agent server may be a microcomputer, a chip card having a microprocessor, and memory. The agent server comprises a plurality of interfaces for connecting to an Internet access terminal, on the one hand, and to an Internet connection device, on the other hand.

Such a configuration is however not limiting and may include "various variants: refrigerator incorporating a microprocessor and memory, autonomous modem, smart card phone, programmable Internet access terminal, programmable router comprising.

The access agent server comprises the following subsystems: a file manager (37), a relational database manager accessible by a SQL query language (38), a database manager persistent objects accessible by an active object serialization protocol (39), an agent library allowing access to the elementary system functions (40), an agent library for implementing the application protocols of the Internet (41), an extensible library of agents for implementing extended access function to a plurality of Internet resources (42), a plurality of secure (43) and customized instanced agent execution environments from the aforementioned libraries.

 The secure and custom instanced agent execution environments each include a message transmission observable (46) operating according to a method described in detail below.

The method of the invention comprises the following steps: establishing a connection between the Internet access terminal (16) and the Internet access agent server (13), launching the request for the terminal of Internet access to the server of access of Internet access agents (13), select on the access server one or more Internet access agents according to the parameters of the request and preference parameters determined for each user, establish a connection the local connection device Internet (24.2), determine for each agent a plurality of requests according to a method described in detail below and transmit these requests over the Internet to a plurality of Internet servers (54), determine for each agent a plurality of requests according to a method described in further detail and recursively transmit these requests over the Internet to a plurality of Internet access agent servers (13.1, 13.2) also connected to Int ernet by a local connection device, reverse recursively the results of these requests, finally provide the Internet access terminal (16) a response to the initial request. The advantageous features of the invention are: to provide, under the simple appearance of transparent access to a centralized local resource, access that actually uses a plurality of distributed, redundant and possibly encrypted Internet resources (54); to provide all Internet users with the means to perform automated Internet access services in the background, including in their absence, - to allow customization of Internet access by sophisticated filtering of query results transmitted by the Internet access terminal, - enable the secure interconnection of local networks over the Internet, enable the deployment of commercial activities without the need for a centralized server, - protect users of access terminals from privacy, - prevent in real time access terminal users (16) when changes occurred in certain Internet resources, - exchange files directly, - facilitate the search for Internet resources (13, 13.1, 13.2 and 54), - allow the direct marketing of user profiles by users. Other advantageous characteristics will become apparent on reading the detailed description below of an embodiment of the method of the invention, with reference to a single appended figure, which illustrates the various means and resources indicated in the implementation. of the process.

In the example below, it will be considered that two microcomputers (16) acting as Internet access terminal are connected by a local network to an Internet access agent server even connected to the Internet by a permanent connection (eg router and frame-relay). A portable computer (87) connected to an Internet access agent server (13.1) itself connected to the Internet by a temporary connection (27) (modem and IP dial-up for example) will be considered.

An isolated microcomputer (90) connected to an Internet access agent server (13.2) -even connected to the Internet by a permanent connection (eg ADSL connection) will be considered Several servers connected to the Internet (54) and offering resources compliant HTTP, FTP, POP, SMTP, IMAP protocols. This protocol list is not limiting and may include other protocols such as CVS, DAV.

It will be considered that each Internet access terminal is capable of managing at least the following protocols: HTTP, FTP, POP, SMTP, IMAP, NNTP, FINGER, TALK, IRC, CSTA IP telephony. This protocol list is not limiting and may include other protocols such as CVS, DAV, IRC.

To simplify the drafting, the acronym SARI will be considered equivalent in the following description to Server Agents Internet Access. The acronym TAI will be considered equivalent in the following description to Terminal Internet Access. The acronym DCI will be considered equivalent in the following description to Device Connection Internet.

Each SAAL (13, 13.1 and 13.2) has several protected execution spaces (43). A protected execution space (43) is a virtual machine in which several agents from the SAAI agent libraries (40, 41 and 42) are instantiated. These instances are persistent, that is, capable of being serialized and stored in the SAAI object database (39), or serialized and forwarded to another SAAI (13, 13.1, and 13.2), or serialized and recorded as a file in a memory card, for example Schlumberger EuroChip type.

The acronym ODB will be considered equivalent in the following description Database object of a SAAI The whole of a protected execution space (43) is also persistent. can be the subject of a serialization be saved in the ODB (39), be transmitted to another or be recorded as a file in a memory card, The acronym EPE will be considered equivalent in the following description to Space In reverse, a (43) can be reconstructed from the ODB (39), a serialized EPE received from another SARI of a serialized EPE previously stored in a memory card file.

Each EPE has an observable message bus (46). The acronym BOM will be considered equivalent in the following description to Observable Bus Message.

A BOM (46) is an EPE resource (43) capable of receiving messages including an identifier of the sending instance, an identifier of the receiving instance, a flag indicating whether to respond to that message or it is an unanswered message, a field that determines the formal typing of the expected response, a list of message parameters, and a list of message properties such as: date, lifetime, priority.

Each BOM (46) transmits a message sent by an agent instance to another instance, providing, if necessary, filtering of messages by observers, described below. A BOM observer is an instance of a particular type that subscribes to the BOM to intercept certain messages transmitted to the BOM. Some observers can implement security policy by intercepting messages for agents that represent system resources such as a local file system and blocking their transmission. Other observers intercept a message transmitted to the BOM and, based on a calculation, retransmit a plurality of messages to a plurality of instances across the BOM, thereby creating interaction between agent instances.

Also, the system of the invention does not include fixed interaction structures within each EPE since all the interactions within an EPE are set up by observers, through the BOM and that these interactions are dynamic.

The selection of the EPE (43) to be used during a request from the TAI (16) is obtained by a method comprising the following steps - determination of the IP number of the TAI (16) choice of a port number for the PROXY agents Choosing a session for HTTP agents Choosing an EPE associated with each socket identifier Choosing a default EPE at a given time There are three main types of agents in the SAAI agent library: system agents ( 40), RFC agents (41), and advanced agents for extending access functionality to Internet resources (42).

The system agents (40) interface the BOM with the system resources of the SAAI. These resources can include: TCP-based Internet access (STREAM agent), access to name servers (DNS agent), access to the relational database manager (38) (SQL agent), l access to the file system (37) (agent access to mass storage devices in raw mode (HD agent), access to system-managed encryption functions (CRYPTO agent), access to lexical, syntactic and semantic word processing functions (TEXT agent).

such list of system agents (40) is however not limiting and may also include various variants: interface agent to a serial port, interface agent to a modem, interface agent to a network connection device telephone, interface agent to a home monitoring device.

RFCs (41) provide the interface between the most common Internet protocols and the POP agent (mailbox), IMAP agent (mailbox), SMTP agent (hypertext transmission), HTTP agent (hypermedia transmission ), NNTP agent (news transmission), TELNET agent (generic transmission of a text protocol), FINGER agent (access to user characteristics), TALK agent (sending instant messages), TIME agent (accessing databases) time), IRC agent (direct communication and discussion groups).

however, this list of RFC agents (41) is not limiting and may also include various variants: access agent to messengers, centralized snapshots (eg ICQ, Internet telephone transmission agent, version management (ex. CVS), real-time newsgroup agent (eg IRC).

In addition to the standard RFC agents (41), agents are also provided in the RFC agent library (41) that interface with higher level application protocols such as DAV, XML-RPC, SOAP, LDAP. Two new industrial application protocols are also part of the invention described: the XMLFS protocol and the XMLHD protocol.

The XMLHD protocol is to simulate a hard disk from one of a plurality of HTTP servers, according to a method comprising the following steps - the XMLHD agent registers with the SAAI host system (13) as. a hard drive-type storage device or CD-ROM of a given characteristic (tracks, sectors, block size) - the XMLHD agent transforms each request sent by the host system to access a block of the storage device thus declared in one HTTP request for reading or writing the concerned block as a binary file on one or more remote HTTP servers (54), - the XMLHD agent provides a cache function to accelerate the access most requested blocks.

The XMLHD agent thus makes it possible to display a plurality of remote HTTP servers (54) as if they were a plurality of local hard disks or CD-ROMs. The XMLHD agent thus makes it possible to dispense with a floppy disk drive or a CD-ROM drive on an Internet access terminal and, by creating a backup copy on a plurality of HTTP servers (54), to have access to its library of CDs, DVDs or other media from anywhere on the planet by means of an Internet terminal connected to the system and method constituting the invention.

The XMLFS protocol is to simulate a file system from a plurality of HTTP servers (54), according to a method comprising the following steps - in write mode, the XMLFS agent cuts each file into a multitude of variable size blocks ,. - in write mode, the XMLFS agent encrypts each block by means of the CRYPTO agent - in write mode, the XMLFS agent disguises each block in sound, text or average image of the CRYPTO agent - in write mode, the XMLFS agent places each block on a plurality of HTTP or FTP servers accessible in write mode - in write mode, the XMLFS agent maintains the list of the locations of each block and directory in a table of the SAAI SQL database (38) (13) - the XMLFS agent regularly backs up the contents of the directory and the blocks list, in encrypted form and possibly cut into several pieces, on one or more HTTP or FTP servers - in read mode, the XMLFS agent assembles decrypts encrypted blocks, disguised them, then assembles them, puts them in a cache and gives them access to the host system - in write mode, the XMLFS agent can never erase previous versions of a file so that it can be consulted versions su ccessives of the same file and ensure an eternal memory function - in write mode, the XMLFS agent can place on the HTTP servers only encrypted files of difference between one version and the next - in write mode, the XMLFS agent can use RSYNC protocol and data compression to speed up transfers - in write mode, the XMLFS agent can call a TEXT agent to obtain a list of keywords stored in the file (before encryption) and transmit this list to an INDEX agent - in write mode, the XMLFS agent can previously buy backup space through a BUY agent.

The communication between SAAI (13) and TAI (16) is generally two-fold initiated by TAI (16) and initiated by SAAI (13). When the TAI (16) transmits requests of any type (HTTP, FI'P, POP, IMAP, PROXY-HTTP, PROXY-FTP, SOCKS) to (13), the SAAI (13) responds to these requests by reacting as an Internet server or as a PROXY server. Conversely, the SAAI (13) can send via the PING FINGER, ICQ, SOAP or TALK protocols requests to the TAI (16) to (induce to consult Internet resources or check its operating condition.) When the SAAI (13) wants to transmit an instant message to the TAI (16), a request of the TALK type is sent and triggers the display of an image, an animation, a text, the opening of an image or an accessible form through a URL specified in the content of the TALK message, agents instantiated in EPEs (43), everything, such as Internet resources, are all referenced by a W3C-compliant URL, which are considered unique in space. However, they do not consider the namespace resulting from the ZDNS agent instantiable in an EPE (43) of the system constituting the invention to be unique.Many resources may have the same name when ZDNS does the union of more In this case, a unique resource is determined by choosing the first resource in the priority order defined by the ZDNS: This order of priority can be modified globally and on a case-by-case basis by priority rules defined by the user within EPE (43) for the ZDNS. Advanced SAAI agents (42) offer extensive Internet access features that do not include IAT (13). They simplify access from a TAI to a multitude of distributed Internet resources (54, 13.1, 13.2), distributed, possibly redundant sometimes encrypted. They simplify the combination of intranets, extranets and multiple internet. The agent CACHE retains in fODB (39) the results of the requests in the form of reified messages that can be activated later or indexed them temporally in a table of the relational database manager (38). In offline mode, as for example the box laptop (87) which is only temporarily connected to the Internet, the agent CACHE allows to consult all the resources already consulted without having a connection to the Internet by simulating the steps of a protocol previously recorded in fODB (39). Thus, with the agent CACHE, it becomes possible to record an Internet session as one records a television program on a video recorder. The CACHE agent is also able to perform type queries in advance according to a user-specified scenario. This makes it possible to download many Internet resources in advance for later access much faster. All resources identified by a URL are also characterized by: a set of keywords belonging to predetermined categories (chosen in the DMOZ Open Directory catalog project), a textual summary, a set of keywords to index, icon, a fingerprint graphic, sound footprint, legal classification (representation rights, publisher author), nature of the resource (representation of a physical object, informational object, information processing service, processing service of a physical object ). The SEARCH agent allows, from a URL, to find an information resource whatever, its place of publication. The SEARCH agent transmits, possibly through an initial chain of type mixmail allowing the anonymization of the request, a search request for a resource identified to at least four other SEARCH agents present on other SAAIs (l3.1). . Based on a similarity assessment, the other SEARCH agents respond if the resource is available in their CACHE or send the request to other SEARCH agents recursively on other SAAIs (13.2), orienting the request accordingly. similarities with previous queries, and a predictor of the most likely provenance path based on the largest similarities. Each SAAL SEARCH agent (13, 13.1 and <B> 13.2) </ B> knows the identifier of the request (to avoid loops) and knows its neighbors only. But the request does not contain an identifier of the initial requestor. Only the first SAAI 13) at the input of the mixmail type of anonymization chain knows this information but does not know the content of the query, nor are they the result; both encrypted. Thus, an information resource can be obtained in complete confidentiality and without it being possible to do so. simultaneous proof of its origin, of its destination, or even of its content. The LOCATE agent is used to determine at a given time the URL of a resource managed by one SARI (13, <B> 13.1 </ B> and 13.2) present in the world. A descriptor is recursively transmitted to all SAAIs (13, 13: 1 and 13.2) interconnected on earth. Each SAAI (13, 13.1 and 13.2) responds either by continuing the recursion, limited by a maximum lifetime of the request, or by using its cache to provide an answer. The response can either be passed directly to the initial requestor (13), or transmitted indirectly by going back in the reverse direction of the recursion chain and, possibly, by integrating a mixmail anonymization string.

The SELL agent makes it possible to publish a resource for sale by specifying its characteristics and a price. In addition to a page with a multimedia description of the object for sale, the SELL agent is able to react to purchase or option requests. It is possible, consolidating the SELL agents into an INDEX agent and allowing LOCATE agents to run a distributed ad system.

The BUY agent makes it possible to place a resource purchase request specified either by its unique identifier or by its characteristics. The agent is only available directly on the SAAI (13) it has been published. It is therefore an agent to set up a system of classified ads distributed.

The AUCTION agent makes it possible to publish a resource for sale by specifying its characteristics, a minimum price and the duration of the auction. It is therefore an agent to set up a distributed auction system.

The REFER agent makes it possible to relate BUY and SELL agents encountered during recursive steps of the SAAIs (13, <B> 13.1 </ B> and 13.2). The REFER Agent may charge a flat fee for this information.

The INDEX agent maintains an index of all resources accessed by other agents. These resources are categorized by keywords, categories, URLs, geographic location when it makes sense, by footprint, by footprint, and by time period. The STOREVER agent provides background backup of local files, relational databases, object databases in XMLFS or XMLHD file systems. The STOREVER agent acquires HTTP storage space through a BUY agent. The purchase can be made anonymous through a pseudonym third party responsible for guaranteeing the transaction by revealing the identity of both parties. The STOREVER agent also provides HTTP storage space on the local file system through a SELL agent.

The STOREVER agent also implements an eternal storage method with long access times comprising the following steps - the content to be saved forever is divided into blocks which are globally redundant and individually incomplete, - each block is then encrypted and provided with an identifier chosen randomly and written on the block - each block is published on the previously acquired distributed storage space, - each block is offered for backup for a determined period through an agent. SELL, - an eternal safeguard contract is then concluded at the pseudonym third party, - at the origin of this contract, the party wishing to save a block (13) deposits a sum which will be transmitted to the party ensuring the backup (13.1 ) when the latter has published the block on a server of its choice accessible by a SEARCH agent - at the origin of this contract, the party providing the backup buys the right backed up by a auction limited to 50% of the sum paid at the end of the contract, e - the block is then kept locally secretly by an unknown SAAI for a specified period, - at the end of this determined period, the SAAI (13.1) makes the block accessible and published through a SELL agent - the STOREVER agent launches a SEARCH agent to retrieve the notified block of the termination of the contract The eternity level is determined by the publication dates. It can be a finite or infinite sequence. In the case of an infinite sequel, the total estimated cost of eternal backup is limited by the exponentially decreasing cost of Internet resources.

The VERSION Agent verifies that the software versions installed on the host system are the latest versions; warns in case of update and possibly performs updates automatically.

The STOCK agent follows stock market evolutions and warns the user of TAI (16) with a TALK in the event of a price movement as described by the user (16). The FILE agent allows the point-to-point exchange of a file, possibly compressed and encrypted. The ADV agent allows the deletion of advertisements in the web pages consulted and their replacement either by other advertisements or by an empty box. The agent detects ad placements either by detecting link syntax or by detecting link locations from template HTML pages. The ADV agent can also delete any images and replace them with locally stored images.

The MCRAWL Agent is exploring Internet search engines to provide a consolidated version based on a single request provided by the user that will be sent to many search engines. The MCRAWL agent can be started at regular intervals and prevented in the event of new documents or substantial changes, thanks to the semantic analysis tools of the TEXT agent.

The SPOTURL agent keeps an accounting of the most visited URLs in an EPE (43) and offers for sale, possibly, the knowledge of this information through a SELL agent.

The SPOTINDEX agent holds a compatibility of the most indexed keywords on an EPE (43) of an SAII (13) and possibly this information for sale through a SELL agent.

The SPOTCON agent evaluates the information transfer performance between SAII (13, 13.1, 13.2), and with other Internet resources (54) and possibly offers this information for sale through a SELL agent.

The ZDNS agent performs a recursive domain name lookup on an SAII network (13, <13.1, 13.2) using EPE-specific local DNS (43). Multiple addresses can be returned for a given domain name. The ZDNS manages homonymy by priority system based on local parameters and data obtained by a FINGER agent on the possible choices.

The HTUNNEL agent is used to encapsulate / unencapsulate a STREAM agent into an HTTP agent. The UFO agent allows to participate in distributed computing processes such as UFO search, breaking encryption keys.

The XTRANET agent provides a routing between two SAIIs over the Internet according to a method comprising the following steps: if the recipient SAAI (13) is permanently connected and has a fixed address, the recipient is contacted to set up a encrypted tunnel, through a HTUNNEL through a PPP link encapsulated in an encrypted STREAM.

- If it does not have a fixed IP address (l3.2), its IP address is determined through ZDNS, possibly by contacting a permanently connected SAAI on which SAAI recipient publishes its IP address on a regular basis - if the SAAI recipient is not permanently connected (13.1), he contacted by an indirect means in a first (eg by sending a phone call on the D-channel of an ISDN connection or an SMS message on GSM) which will then trigger the connection of the destination DCI (13.1).

The PROFILE agent establishes a simplified vision of the usage patterns of an EPE (43) based on manually entered information and information provided by the SPOTINDEX, SPOTCON and SPOTURL agents. This PROFILE information is eventually offered for sale through a SELL agent.

The NEWS agent continuously searches for new information published on a list of HTTP sites, NNTP groups, and sorts according to user-defined rules based on TEXT agent word processing capabilities. .

The PHONE agent transmits or receives a telephone call or fax from the TAI (16) to another SAAI (2) connected to a telephone network, based on cost and quality of service parameters obtained by SPOTCON. The SAAI (13.2) receiving a telephone call via the Internet makes a connection with the telephone network to which it is connected and charges the issuer. The PHONE agent also allows the direct linking of TAI (16) to TAI (87) through SAAIs (13 and 13.1) providing the encryption.

The IMESSAGE agent consolidates direct communication requests from ICQ, TALK, IRC agents by communicating with the TAI using HTTP, FINGER, SOAP and TALK agents: It is thus possible to answer several requests for dialogue from services and consolidate directory access. The IMESSAGE agent also offers the ability to create aliases from one service to another and thus provide perfect interoperability between instant messaging services.

The COST agent browses an Internet resource and extracts the costs automatically. Combined with a LOCATE agent, it allows you to compare costs.

The CLUST agent connects a plurality of SELL agents and an important agent during a LOCATE request.

The BACKSCREEN agent produces displayable images in the background for viewing information produced by other agents.

Agent PATSOURCE browses all SAAIs (13, 13.1 and 13.2) and Internet resources available to search for source code that could constitute a supply of patent counterfeit means, by comparing comments, -the names of line functions code based on Espacenet patents by means of the lexical, syntactic and semantic comparison functions of the TEXT agent.

The TRAD agent provides an interface between the CACHE agent and an online translation server to transparently provide translation of the Inner sites. Thus no longer is it necessary to acquire automatic translation software.

The ANTISPAM agent eliminates natural language e-mails passed through a MD5 signature or imprinting agent as a result of a number included in a finite set of values specified by the user. In addition, the ANTISPAM agent has a semantic comparison function with a text and style database that uses word processing resources provided by the TEXT agent. More precisely, the ANTISPAM agent can use two methods.

A first method of eliminating unwanted e-mails comprises the following steps: evaluation of a fingerprint of the textual message according to a type method, comparison with a fingerprint database, elimination of messages whose fingerprints are part of the database; fingerprints.

A second method of eliminating unwanted e-mails comprises the following steps: transforming each word of the e-mail into an integer identifier from an associative dictionary specified by the user and managed for example by a database; an error correction code on the sequence of numbers, except the last adjective, -, elimination of the message when the corrector code is equal to the code of the last adjective.
