Abstract

The present invention relates to a method of controlling access to a service for a plurality of users. Each user has access rights owned by each user and has a portable object that emits a radio signal that identifies each user. The service is selected at the level of the device. The device receives a code to identify the current user and to verify each user's access rights. Access rights are collected to determine if the service can be assigned to all current users. According to one improvement, the set assigns access to the service if the service is granted to the current user with the least privileges. According to one variant, access to the service is granted if at least one current user can access this service. The invention also relates to a device capable of controlling access to a service when a lifetime user is around the device.

Description

METHOOD OF CONTROLLING ACCESS TO A SYSTEM BY A PLURALITY OF USERS, AND SYSTEM AFFORDING ACCESS TO SERVICES

The present invention relates to a method of controlling access to an audiovisual system through a plurality of users, and to a device capable of managing access control according to the method.

Today, many audio visual channels can be accessed through television receivers. Younger viewers can choose a program for the information-savvy public or even for adults. This is why recent receivers are equipped with a function known as a "parental control" function that allows access to some broadcast documents to be restricted.

In general, personal computers allow connection to multiple sites via an Internet network. Documents, for example simple text, or photos, or audio content, or audiovisual content, may be restricted from broadcasting. Indeed, documents marked "adult" or "confidential" due to pornographic characteristics should not be accessed by unauthorized individuals. A solution that allows access to a device or document to be controlled is to lock the device or document using a password. Once the password has been entered and verified with the keyboard, access is granted to obtain a particular item of information, the download of a file or document, the viewing of content, and the like. However, passwords can be given to others, and this fact does not allow access to specific users to be transferred.

One way to realize selective access control is for each user in front of the device to identify itself using a code, for example by entering a number on the remote control. The user who manages the device inserts access rights for other users, for example, the parent restricts the access rights of the television decoder to the young child. Another way of performing selective access control is in the service provider itself, which limits the access rights of the user.

Another solution is for the user to have a secure and personal smart card. The user inserts the user's smart card into the drive of the device and identifies the user through the user's password. The fact that the security information is only recorded on the smart card allows only access to the holder of this card to be granted.

However, when this operation is repeated regularly, the insertion of smart cards can be tricky. Contact free cards or microwave tags, commonly known as "RF_ID" tags, avoid insertion operations because these cards or tags talk through a waveform on a fixed basis. These objects include integrated circuits connected to the coils. For example, the coil is a copper wire on a printed circuit. The coils affected by the electric and / or magnetic fields generate a current, which powers the integrated circuit, making it possible to transmit items of information through the same coil. In a simple specific manner, an integrated circuit includes a memory and a read element for code written to the memory. This code can be superimposed on the electromagnetic field, transmitted in series and captured by the antenna. Because this code identifies the circuit, if the circuit is coupled to the object, the object is also identified by the code.

The application of microwave tags is increasing. For example, these tags are fixed on or integrated into an object for payment at a cash register without human intervention in the supermarket. Very low cost tags can be combined with so many objects that a very wide spread is achieved. As a result, most users carry a micro tag that transmits the determined code. This particular code can typically be used to identify the owner of an object, which is an item of clothing or jewelry or any object worn by the owner. Once the intended use of the implantation is complete, the tag is no longer used for any purpose. It would then be possible to combine the code sent to the user in an audiovisual system equipped with a detector of RF_ID object presence. Once the combining is performed, the audiovisual system can identify any user located nearby. However, when there are several users with different access rights, it is not easy to limit the access rights.

European patent EP 1 760 621, filed by SAP AG, describes access control to confidential information. People carry RFID tags that contain codes that define a level of security associated with a person. If a user who is not authorized to view the item of information on the screen is detected in the vicinity of the screen, the screen is automatically suppressed and nothing is displayed. In this way, even if an authorized person is present, the information will not be displayed for unauthorized persons.

US Patent Application No. 2003/0327243, filed by GRUTESER, describes an information viewing system currently visible through a plurality of people. Certain levels of reliability are combined with documents. The person has an RF_ID tag that enables identification of this person. If the person detected by the tag is not authorized to view the information, the information is not displayed. Likewise, if a person is detected by other means, for example a camera but does not have a microwave tag, the person is considered to be not authorized.

The present invention makes it possible to use tags or cards that communicate without contact, in order to realize access control considering the access rights of each current user.

OBJECT OF THE INVENTION The object of the present invention relates to a method for controlling access to a service provided by a device, which is intended for a plurality of users with specific access rights and is located at a distance enabling the reception of a signal transmitted by a wireless transmission means. Each user carries at least one of the radio transmitting means for transmitting a particular code, the method further comprising

Selecting a service combined with an access right,

Receiving a code sent by a wireless transmission means carried by the user via the device,

-Identifying the current user via the received code,

Collecting access rights of all users identified by the code sent by the transmitting means, and

Accessing the selected service if the code of at least one current user authorizes access to the service

It is characterized by including.

In this way, following the selection of the service, the device detects the user in the vicinity and collects access rights in a manner that grants or does not grant access, depending on the current user.

According to one improvement, the set of rights grants access to services that the current user has access to individually. In this way, the service provided by the device takes into account the access rights of each current user. According to one variant, one of the users has private access to the service, and access to this service is granted to that user only if the user is a current user. In this manner, it may be possible to exclude access for one user when another user has private rights to the selected service. In accordance with this variant, the service for which access is private only is restricted in time or granted during a given event, which access is then granted to other current users around the device at the end of the determined time or event. In this manner, the device automatically detects the end of the personal right, for example the end of the spread of the program, and following this period or event, provides universal access to the current set of users.

According to a third variant, if access to a service is coordinated by payment, then the set of rights is granted to such service if all current users access it individually, and if one of these users pays access to it. Grant access.

In addition, the present invention provides a plurality of users who have a specific access right and are located at a distance to enable reception of a signal transmitted by a radio transmission means, each user carrying at least one of the radio transmission means for transmitting a specific code. An electronic system for delivering at least one service to a plurality of users is provided.

Means for selecting services combined with access rights,

Means for receiving a code transmitted by a wireless transmission means carried by the user,

Identification means of the current user via a code transmitted by the wireless transmission means, and

Means for collecting the access rights of all users identified by the code sent by the sending means, and means for allocating access to the service if the code of at least one user currently authorizes access to this service;

It is characterized by including.

Such a device causes a service selection command to be received, a user to be detected, and access rights to be collected in a manner that grants or does not grant access to these services depending on the current user.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in more detail within the scope of the following description of embodiments provided by way of example with reference to the accompanying drawings.

The present invention provides a method and system for controlling access to a device, such that if a user watching a broadcast has a low privilege value, the user is filtered out to view the broadcast, and a viewer with a high privilege value has this privilege. According to the value, the system does not receive any preparation for watching all broadcasts, and in the case of multiple viewers, the broadcast is adjusted accordingly.

5 is a flowchart of steps according to an embodiment.

In the description that follows, the term “electronic tag” refers to any communication that communicates without contact, regardless of whether it is a smart card, an electronic tag (or “wireless tag”), or an abbreviated form of Radio Frequency Identification (RFID). Contains an object. The wireless tag consists of an electronic circuit and an antenna. The electronic circuit includes the code written to the memory. The coil enables both power supply and communication of the circuit. When the tag is placed in the electromagnetic field, the circuit is powered and sends the code to the antenna automatically and serially. The code of the tag is similar to a barcode according to ISO standard 15693-3. In the embodiment described below, sixteen last hexadecimal codes may be used.

There are many kinds of wireless tags available in the market. Passive and active tags exist, which have a power source (cell, battery, solar cell, etc.). The "current" passive version can operate from 125 to 135 KHz and can signal from a few cm to 0.5 m. Still more sophisticated versions of the passive type operate at 13.56 MHz (ISO 15693-3) and can signal up to several meters. Finally, there is a version that runs at 8.68GHz and can signal up to 50m. Two examples of wireless tags exist below: The "NetLabel" model manufactured by NEC is characterized by a size of 0.8 mm ² , an integrated antenna, 1024 bits of memory, a communication frequency of 2.5 GHz, and Hitachi. The model "Myu", manufactured and sold by the company, is characterized by a size of 0.2 mm ² , an integrated antenna, 128 bits of memory and a communication frequency of 2.5 GHz. The wireless tag is intended to be placed in a general purpose consumer product such as, for example, a food product or clothing. Versions that can be detected at several meters are used for tagging of more expensive products, such as leather jackets, silk scarves and the like. Very small size of this tag (from 2 mm ² or 3 mm ² to 0.1 mm ²⁾ ), The tag is substantially impossible to detect with the naked eye. Thus, the buyer has no reason to remove these tags.

1 illustrates a prior art structured in a standard manner of use of a wireless tag associated with an object. The wireless tag is attached or attached to the object to which this tag is referenced. Tag readers (detection portico, hand-held readers, detectors on the shelf) connected to the local server allow the inventory of the object to be counted, identifying the purchase by the user at the last minute.

The invention will be described below in the audiovisual domain, which does not exclude other domains similar to the network computation domain. 2 shows an electronic system comprising several devices including a device 1 for providing access to a service and a display device 2. The device 1 is a central processing unit 3 connected to a memory 12 consisting of read-only memory (ROM), random access memory (RAM) and non-volatile memory such that user access rights are retained such as data. It includes. The device 1 also has an interface 5 for communicating with a high bit rate digital bus 6 which allows audio / video data to be transmitted in real time. For example, such a network is an IEEE 1394 network. The digital bus also allows data to be sent to the server. The receiver also receives audio / video data from the broadcast network via a receive antenna coupled with the demodulator 4. The device also comprises an infrared signal receiver 7 for receiving signals with the remote control 8 and audio / video decoding logic circuits 10 for the generation of audiovisual signals transmitted to the television screen 2.

The device 1 also has a clock 9 and circuitry 11 for data display on a screen, often called an On Screen Display (OSD) circuit. The OSD circuit 11 is a text and graphics generator that enables the display of menus, pictograms (eg, numbers corresponding to displays) on the screen, or allows two audiovisual content to be mixed. The OSD circuit is in particular controlled by the central processing unit 3 combined with the tag management execution module. Such program modules are typically implemented in the form of modules of executable code remaining in ROM 12 and data written to RAM. In addition, the program module may be realized, for example, in the form of a dedicated circuit of the ASIC type. The device 1 is connected to a radio interface 13 which comprises an antenna which enables contact via radio-frequency with a radio tag found within a certain operating radius and which enables receiving a code recorded in memory from the radio tag. do. The operating radius of the antenna provided in the device 1 is directly proportional to the output of the electromagnetic field transmitted by this antenna. At present, the operating radius is about 3m. The antenna of the device 1 is preferably directed to the front for detecting a tag located in front of the device. If the room has three antennas spaced at a certain distance from each other, using the output of each antenna, the system can triangulate to determine the location of each tag. During the learning phase, the device may indicate the location of each tag, allowing the person carrying the tag to easily identify itself within the group of users.

3 shows an example of a system for detection of a wireless tag installed in a room, for example a living room. The system is implemented in a decoder connected to the television screen. In the example of FIG. 3, the electromagnetic field detects tags carried by three users, two tags are applied on two armchairs, one tag is applied on a sofa, and one tag is fixed to a flower pot. do. Initially, the system attempts to identify the person carrying the tag. The system then uses the items of acquired information to associate them with access rights and possibly user profiles detected adjacent to the device.

Thus, the first step is to associate the code sent by the tag with one or more users. This is only possible if the tag is carried by the user and not fixed to the fixed object. A picture hanging on a wall or a tag fixed to an electrical device in a home cannot be used to identify someone. Thus, the system analyzes the tags entering or exiting the volume covered by the interface antenna 13 through learning. As soon as a change occurs in the environment of the tag around the device 1, the learning phase is adjusted. This step is to identify the set of tags that respond to the transmission of the electromagnetic field emitted by the antenna of the device 1, and to associate this tag with a clearly identified user, or possibly an object.

During installation of the system in the room, the system performs a search of all tags present within a certain operating radius. According to a preferred embodiment, the system comprises a device 1, a control screen 2 and a keyboard connected to or connected to the device 1 for receiving a user's command (eg a remote control 8). . Another user interface may be, for example, a speech synthesizer combined with a speech recognition system to collect information of the user. At initialization, the device 1 analyzes the environment of this device and receives a code of a specific number emitted from the tag. The code and the code of the code sent by the tag are displayed on the screen 2. Advantageously, this information appears as a window on the screen where the image is not important, for example, which can be positioned in the lower left area of the screen. The user then enters or exits the tag detection radius emitted by the antenna. Regular, at intervals that can be adjusted from one second to several minutes—the optimal result given by the indication is approximately three seconds—the device 1 activates the wireless interface, which allows the tag to transmit the code of the tag. Emits an electromagnetic field. Once all the codes have been received, the program module compares the last scanned code with the set of received codes. If the change occurred in the middle, i.e. when the tag appeared or disappeared in the field, the learning phase is initiated by displaying a banner on the television screen 2. This banner indicates the status of the change to the user in front of the screen. In particular, two message types are found:

Message I

Message Ⅱ

사용자가 시스템에 접근할 때 메세지 Ⅰ이 나타나거나, 사용자가 멀어질 때 메세지 Ⅱ가 나타나는 것을 주목한다면, 사용자는 사용자의 식별자 또는 사용자의 이름을 삽입함으로써 디스플레이되는 태그 코드와 자신을 결합시킬 수 있다. 식별자는 1 내지 9의 번호를 갖는다. 이름은 모든 문자를 나타내는 메뉴, 방향 키를 사용하여 문자 상에 위치 지정될 수 있는 커서, 그리고 커서 상에서 문자를 확인하는 "OK" 키를 사용하여 한 문자씩 삽입될 수 있다. 또한, 사용자는 객체를 검출 반경으로 이동시킴으로써, 종류 I의 메세지의 디스플레이가 초래된다. 객체가 적절히 배치되어 있고, 사용자가 객체의 자세를 취하면서, 메세지 Ⅱ의 출현을 야기하는 것 없이 철회한다면, 이 사용자는 태그가 객체에 적용되어 있다고 결론 지을 것이다. 그런 후에, 사용자는 키보드를 사용하여, 이 태그가 사용자에 결합되어 있진 않지만, 고정된 것으로 고려되는 객체와 결합되는 것으로 나타내는 코드 "0"을 삽입한다.

If you notice that message I appears when the user accesses the system, or message II appears when the user is away, the user can associate himself with the displayed tag code by inserting the user's identifier or the user's name. The identifier has a number from 1 to 9. The name can be inserted character by character using a menu representing all characters, a cursor which can be positioned on the character using the direction keys, and an "OK" key confirming the character on the cursor. The user also moves the object to the detection radius, resulting in the display of a message of type I. If the object is properly positioned and the user withdraws the object while posing, without causing the appearance of message II, the user will conclude that the tag has been applied to the object. Then, the user inserts a code "0" using the keyboard, which indicates that this tag is not associated with the user but is associated with an object that is considered to be fixed.

The utilization step of the tag management system according to one simplified embodiment is found in the electromagnetic field emitted by the device 1 or by another device receiving data associated with the tag code from the device 1 and an associated user identifier. This step shows a list of identifiers associated with each tag. The list appears, for example, in the form of a window appearing on the upper left of the screen 2. 4 shows the appearance of a screen with a window in the upper left portion indicating the status of the different tags detected. The window contains the following message:

Message III

This text includes the tags associated with Viviane, two tags associated with Jocelyn, 17 tags associated with the object (15 tags for DVD), and the last two detected tags. It is not yet associated with a user or object during the learning phase. The appearance or disappearance of such windows is controlled by specific keys of the remote control 8. Another way for this control, perhaps in compliance with the first approach, is that a window with each change appears and disappears after a duration that can be programmed, for example 10 seconds. If the device is only an audio type, it is produced by the speech synthesizer and a message of the same content as the previously described message is emitted by the device. The program on the screen background considers the rights of two recognized users.

After a certain time, the device 1 builds a correspondence table that associates the tag reference with the identity of the user. The display of the window shown in FIG. 4 indicates a person identified by the system.

Each person who can use the audiovisual system 1 has access rights recorded in the memory 12. There are several ways in which this permission can be inserted. For example, an administrator launches a configuration menu that represents a menu by user name and inserts access rights for each user. Here, an embodiment of the present invention is described using a simple means of determining authority in the audiovisual area: namely, a grade of 1 to 4 of morality level, where grade 1 is a document that anyone can access. And Grade 4 is a document that only adults can see. The memory 12 of the device maintains a table that combines the identity and moral level of the user in the non-volatile portion 1. If the user is a young child, this child's associated level is 4; if the user is an adult, this adult's level is 1. If the person detected in front of the device 1 has a moral level of, for example, a value of 2, the device provides access only to documents having only a moral value of 1 or 2 as an attribute.

According to one preferred embodiment of the present invention, if a user of lifetime appears, the device 1 compares the moral level associated with each user and, according to a first strategy called a "restrictive" strategy, 1) will select the person with the most restricted profile as a reference. For example, if a young child is found among the users, the moral level is this young child's level, i. However, if the device 1 detects three adults each associated with the highest privilege level, then the reference value is the maximum value: 4. As a result, according to the set of users, the set of rights is indicative of the rights of the user with the minimum value.

Table 1 below illustrates the limiting strategy:

user Permission value One 4 2 4 3 One (1 + 2 + 3) One

The invention will be better described using FIG. 5, which shows a flow chart of the steps of an executable program module through the device 1, according to one embodiment. For example, such a device is a television decoder designed to receive audiovisual services.

Initially, the user uses the remote control 8 to select a service, for example an audiovisual channel (step 5.1). In step 5.2, the device receives a code sent by a tag indicated in the device's environment. Using the previously described joining step, the device identifies the current user and extracts the user's access rights from memory 12 (step (5.3)). In step 5.4, device 1 collects the access rights of the current user. The restriction strategy described previously is to compare all access permission levels and maintain the most restricted level. Other strategies herein are described below. The device then tests whether the collected rights authorize viewing the broadcasted program via the selected service (step 5.5). To do this, the program module compares the collected rights with the access rights associated with the broadcast program. If access to the program is authorized, the selected service is assigned (step 5.6), and if access is not authorized, the selected service is not provided (step 5.7). In the latter case, the message informs the device's decision using the message displayed. Advantageously, the message indicates who of the current users is not authorized to use the service. Such a message is of the following kind, for example:

Message IV

Thereafter, during step 5.8, the device 1 periodically analyzes the presence of the tag and remains in the same state unless an appearance of any new tag or disappearance of any tag occurs in between. When a change occurs, the device skips step 5.2 to perform a new detection of the current tag and a new collection of access rights of the user identified by the tag. Thus, the program will repeat continuously until the device is turned off.

Another strategy makes it possible to calculate a set of privileges. It is assumed that the device authorizes the payment service and that one of the users is a subscriber with access to this service. Thus, a user can provide rights to other current users. According to this strategy, called a "widened" strategy, the set of rights lies in the rights of the user who owns the maximum, depending on the current user.

Table 2 below shows the expanded strategy:

user Permission value One 4 2 3 3 One (1 + 2 + 3) 4

According to Table 2, User 1 with the highest privilege value gives the privilege to another user. Thereafter, even if a user who has obtained access to the service leaves, the remaining user can continue to access the service because the service has been paid. Interruption of access occurs at the end of service or when the device is turned off.

In one or the other of the extension or restriction strategies, access rights may be limited at the program level, at the service provider level, or at the level of the document creator. For example, it may be possible to refer to an audiovisual channel with a universal level of authority, where a cartoon channel for children will be referred to as level 1 no matter what program is broadcasted. Another example is an example of a particular Internet site of pornographic nature, and access to this site is restricted to adults, whatever the user's request to proceed to this site.

In the description so far, the access rights of a user are considered to be limited in terms of access to the service in relation to other users. According to another strategy, called a "personal" strategy, a user's access rights include signals that define personal access to the service, i.e., consider the possible presence of other users. This strategy is implemented, for example, when a user has a subscription to enable access to an Internet site, which enables, for example, the downloading and on-line playback of audiovisual documents. The service provider may request that access to the provider's site be restricted to subscribers only. If the device 1 detects the presence of a user other than the subscriber for this service, access will be denied. This strategy can result in the following situation: each of the two subscribers has private access to the service, and the two services are different. If two subscribers are together, they do not have access to any services, but if they are alone in front of the device 1, each subscriber has access to the subscriber's services.

Table 3 below shows the personal strategy:

user Permission value One Service A_private, Service B 2 Service A, Service B_private 3 Service B, Service A (1 + 3) Service b (2 + 3) Service a (1 + 2 + 3) ---

According to Table 3 above, a lifetime user can access the service only if none of the subscribers have personal access to this service.

According to this strategy, a user has personal rights without limitation, for a determined period, or during a determined event. For example, a user is authorized to receive an event, for example an audiovisual program, and to watch the program. Then, access to the channel broadcasting such a program is made private.

How to allow a wireless tag to identify the user carrying the tag has been described previously. According to one refinement, the wireless tag also includes a programmable memory containing access rights associated with the user. Upon detection through the device, communication is established that enables the tag to transmit the user's rights to the device. In this manner, the device does not need to maintain a database to combine with the user, the user's identification code and the user's authority. The wireless tag then acts to identify the user and send the user's rights. Secure communication between the tag and the device is advantageously implemented, avoiding any frauds. Such communication is of the same kind, for example, between a contactless smart card and a card reader providing access to a service.

The present invention relates to any device that allows access to a program at a remote site, to an audiovisual channel, and to a game, and generally delivers a personalized service from a user. In addition, the present invention can be used to suggest a list of services that can be accessed according to a user's access rights to a current set of users. The display of the list of proposed services includes two parts, the first part representing a service that can be accessed without specific conditions and the second part including a payment service requiring that consent of at least one user be provided. do. Access rights do not define preferences between one service or another, ie whether a service can be accessed. Advantageously, the services that can be accessed are described in order of being a function of the current user's preferences. These preferences are stored in the device 1 or downloaded from the smart card carried by each user. In this manner, between services that can be accessed, if some services clearly correspond to the current user's preferences, these services will appear first in the displayed list.

The embodiments of the invention mentioned above were chosen for the practical nature of the embodiments. However, it is not possible to provide a full list of all embodiments covered by the present invention. In particular, each step or all means described may be replaced by equivalent steps or means without departing from the scope of the present invention.
