Description

Technical field

The invention relates to systems and methods for determining the level of confidence of a URL received from a transmitter.

State of the art

With the development of mobile devices and the Internet of Things (Internet of Things, IoT), technologies are developing that allow the interaction between digital technologies and physical objects. One such technology is QR codes. A QR code is a picture containing encoded information. Codes are usually located in storefronts, museums, airports and contain encoded text or a web service URL that is related to the property. A web service may, for example, contain information about discounts in a store, an overview of the museum exposition, information about flights at the airport, etc. The disadvantage of this technology is that the user needs to go directly to the QR code and take a picture of him to get the information encoded in the QR code. Another similar technology is based on the use of RFID tags and NFC, but the range in this case is limited to 10 centimeters.

These shortcomings are solved in developing technologies for transmitting data from wireless transmitting devices - beacons (English beacon) and the Physical Web concept (URL transmission, English Uniform Resource Locator). Wireless transmitters transmit a limited set of data at specified intervals using wireless communications (typically Bluetooth Low Energy - BLE). The cost of such transmitters is small, and the operating time from one battery reaches several years. The distance over which data can be transmitted is usually limited to ten meters if BLE is used. Therefore, to obtain data, the user does not need to perform any actions, it is enough for him to be in the access zone of the transmitters, which is limited to a distance of ten meters.

The transmitters are used, for example, for geolocation in enclosed spaces where there is no satellite signal, as well as for sending advertisements about objects located near the transmitter (for example, information about discounts in the store). For geolocation, many transmitters are evenly placed in the room, each of which broadcasts predetermined coordinates of its location. The receiving computer device receives data from several nearby transmitters at once and, using data on their location, as well as analyzing the signal power from each transmitter, determines its own location with the necessary accuracy.

When using transmitters for advertising purposes, they are placed near the store and broadcast information to attract customers. For example, a URL (Uniform Resource Locator) can be passed that leads to the store’s website or to a web page containing information about store discounts, etc.

Some of the most common standards for translating data using BLE include: iBeacon, AltBtacon, and Eddystone. The Physical Web concept can use AltBeacon and Eddystone. An Eddystone format data packet, for example, is 64 bytes in size and may contain the following data structures: unique transmitter identifier UID (Beacon ID); URL telemetry data (TLM), such as the voltage of the transmitter’s battery, its temperature, the number of packets sent since it was turned on, and the time since it was turned on; a periodically changing EID (encrypted ephemeral identifier) used to ensure the security and privacy of devices. EID is rarely used.

It is worth noting that all these protocols also transmit the value of the transmit power level, with which you can measure the distance between the transmitter and the receiving computer device.

Due to the fact that the main data transmitted by the transmitters are web page addresses (URLs), and to receive them, it is enough for the receiving device to have a wireless module (usually Bluetooth), Physical Web technology is easily integrated into existing infrastructure of mobile devices. At the moment, all the most common web browsers and operating systems (Android, iOS) support Physical Web technology. When the transmitters are in the reception area, a notification and information (URL) broadcast by the transmitter are displayed on the screen of the mobile device (in some cases, it is necessary to additionally install the corresponding application).

At the same time, due to the simplicity of the technology, it can be easily used by intruders. Because Since most transmitters are designed only for data transmission and cannot receive data on their own, it is difficult to authenticate and verify the authenticity of both the transmitters themselves and the data that they transmit. In addition, any smartphone with a Bluetooth module and the necessary software (software) can act as a transmitter.

An attacker can place his transmitter next to a well-known (trusted) transmitter located near the store. At the same time, the URL broadcast by the attacker’s transmitter can direct the user of the mobile device to a fake store’s web page with fraudulent or malicious content. And in geolocation systems, a transmitter installed by an attacker can transmit invalid coordinates. In order not to be detected by antivirus applications, attackers can place malicious content at a well-known cloud provider and in this case the URL will not be contained in the list of malicious URLs of antivirus companies. Detection and blocking of receiving data from a specific transmitter is not always possible, because the transmitter can change its UID. In addition, checking the content at the URL does not always allow us to determine the fact of fraud, as URL may not contain fraudulent content. But at the same time, an attacker, using information about a real object, such as, for example, a store, can save the URL to the transmitter, which will direct the user to a fake store website containing, for example, a registration form into which the user must enter his personal data that could then be misused by an attacker. Thus, a technical problem arises in determining the level of trust of the URL received from the transmitter and intended to restrict access to the URL. The level of trust in this case can be used to control access to the URL that was received from the transmitter on the user's computer.

In the prior art, there are technologies that solve similar problems. For example, in the application US 20160050219, a method is described for detecting malicious transmitters, namely, transmitters sequentially broadcast two messages, one of which contains the identification data of the transmitter, and the second message contains encrypted data necessary to authenticate the transmitter using a remote server and receive the broadcast message transmitter. However, the URL is often transmitted in unencrypted form and, in addition, authentication data is rarely used in transmitters. Therefore, the technology described in the application only works if the transmitters are programmed for the data transmission puncture described in the application and will not work with many other transmitters. In addition, the technology does not determine the level of confidence in such transmitters. Thus, the technology described in application US 20160050219 does not solve the above technical problem.

Analysis of the prior art allows us to conclude about the inefficiency and, in some cases, the impossibility of using previous technologies, the disadvantages of which are solved by the present invention, namely, systems and methods for determining the level of confidence of the URL received from the transmitter.

The implementation of the invention

The objects and features of the present invention, methods for achieving these objects and features will become apparent by reference to exemplary embodiments. However, the present invention is not limited to the exemplary embodiments disclosed below, it can be embodied in various forms. The essence described in the description is nothing more than the specific details provided to assist the specialist in the field of technology in a comprehensive understanding of the invention, and the present invention is defined in the scope of the attached claims.

In FIG. 1 shows a system for implementing the invention, namely, a system for determining the level of confidence of a URL received from a transmitter, a device that broadcasts the URL through a wireless channel. An application 111 is installed on a computer device 110 (for example, a personal computer, smartphone, laptop, tablet, etc.), which is connected via a network 150 to a remote server 130. Application 111 is designed to receive URLs from a transmitter 120. It should be noted that in the general case , there may be several transmitters 120. In addition, application 111 is designed to transmit to the remote server 130 the received URL and URL parameters that contain the date and time the URL was received, as well as a unique identifier for the computer device 110 (for example, MAC address of) and determined using the application 111. The transmitter 120 is a standalone device, carrying broadcast data through a wireless communication channel. Such a device can be, in particular, the so-called “beacon” (English beacon), which transfers data using the Bluetooth wireless standard using one of the protocols: iBeacon, AltBeacon, Eddystone. It is worth noting that the above example of the transmitter 120 is only for understanding the present invention and does not limit the possible implementation options of the transmitter 120. The transmitter 120 can operate using any other wireless standard (Wi-Fi, LTE, etc.) and using any other protocol data transmission.

In a particular embodiment, the operating system (OS) of the computer device 110 comprises an embedded application (not shown in the figure) for receiving a URL from a transmitter 120. In one example, an application 111 receives a URL from an embedded application. In another example, application 111 receives a URL directly from transmitter 120 by intercepting system calls responsible for receiving and processing data from transmitter 120. Hereinafter, for convenience of describing embodiments of the invention, the purpose of application 111 is identified with the purpose of computer device 110. That is, a computer device is intended to receive the URL from the transmitter 120, means that the application 111 on the computer device 110 performs the specified function.

The remote server 130 serves to store the received URL and the received parameters in the parameter base 140. Before the remote server receives the URL, the parameter base 140 already contains at least one URL and its corresponding URL parameters. In a particular embodiment, the parameter base 140 contains at least one other URL different from the received URL and the corresponding parameters of another URL. This condition is necessary for the subsequent determination of the level of confidence in the URL, which will be described in detail below. The power of linking a URL to itself can, for example, take a minimum or maximum value. The remote server 130 assigns a fame level received from the computer device 110. The level of fame is a parameter, the value of which depends on the number of computer devices 110 that have received and transmitted the URL. It is worth noting that the number of computer devices 110 is calculated using the unique identifier of computer devices 110. Moreover, the popularity level of one URL is equal to or greater than the level of popularity of another URL if the number of computer devices 110 that received the first URL exceeds the number of computer devices 110 that got the second URL. In one example, the fame level can take integer values in a given range (for example, from one to ten). Moreover, the level of fame is zero when the number of computer devices 110 that have received and transmitted the URL to the remote server 130 is equal to one. The fame level is ten when the above-mentioned number of computer devices 110 exceeds a predetermined value (for example, 1000).

It is worth noting that in different implementations, the number of computer devices 110 can be calculated in various ways. In one example, the number of computer devices 110 is equal to the number of unique computer devices 110 that have received the URL in question at least once, i.e. the number of unique identifiers of computer devices 110. In another example, if one computer device 110 received the URL in question, for example, ten times (i.e., the parameter database contains ten entries with the URL in question and the unique identifier of one computer device 110), then the number of computer devices 110 will also be increased by ten.

The remote server 130 for the received URL and for each other URL from the parameter base 140 assigns the communication strength between the received URL and the other URL. Communication power is a parameter whose value depends on the parameters of both URLs and on the number of events when both URLs were received by the same computer device 110 within a given time interval (for example, both URLs were received with an interval of one minute). In this case, we can say that both URLs “met” at the same time by one computer device 110. The dependence of the communication power on the number of specified events when both URLs “met” at the same time can be linear. In one example, the communication power can take real values in a given range, for example, from zero to one. At the same time, the power of communication between the two URLs is zero if both URLs did not “meet” together - i.e. have never been received by the same computer device 110 for a predetermined period of time (e.g., 1 minute). At the same time, the communication power is equal to one if both URLs always "meet" at the same time, i.e. always when the device received one of two URLs, it received the second of two URLs during the specified time interval. The receipt of two URLs by one computer device 110 within a given time interval indicates that two different transmitters transmitting different URLs are located in the reception area of computer device 110.

As a result, the remote server 130 determines the level of confidence in the received URL depending on the level of popularity and the power of communication with other URLs from the parameter database 140. The level of confidence in the URL is a parameter that takes real values and characterizes the popularity of URLs among users of computer devices 110 (URL popularity is determined by the frequency of access to the URL) and, as a result, can be used by application 111 to control access to the URL.

Next, the remote server 130 sends a certain level of trust to the received URL to the application 111. The trust level is then used by the application 111 to control access to the URL.

After receiving the level of trust from the remote server 130, the computer device 110 controls access to an information resource on the network at the received URL depending on a certain level of trust in the URL.

In yet another particular embodiment, the level of trust can take one of two values - trusted or untrusted. The URL is trusted when the fame level is higher than the specified value (for example, 3), and the communication power with at least one other URL is higher than the specified value (for example, with at least two URLs the communication power must exceed 0.3). In all other cases, the URL is untrusted.

In a particular embodiment, access control to an untrusted URL is to block at least a portion of the content located at the URL. For example, if a web page at the URL contains malicious JavaScript code, it will be blocked. In this example, the remote server 130 further comprises an anti-virus scan tool that performs anti-virus scanning of the content located at the URL (for example, web page elements, JavaScript, etc.). Having detected malicious content at the URL, the remote server additionally sends this information to application 111, which blocks malicious content.

In another particular embodiment, the control of access to an untrusted URL is to block the display of the URL to the user of the computer device 110. In this case, upon receipt of a data packet from the transmitter 120, the application 111 will not display a notification to the user about this URL. In another example, application 111 can only display a portion of the URL.

In yet another particular embodiment, access control to an untrusted URL is to prohibit the transfer of the URL to third-party applications installed on a computer device.

In one particular embodiment, the control of access to an untrusted URL is to display a warning to the user of the device 110 about the level of trust of the URL.

Trusted URL access control consists in providing third-party applications or a user of the computer device 110 access to the URL.

In yet another particular embodiment, the URL parameters further comprise location data of the computer device 110 at the time the URL was received. In another particular embodiment, the level of fame additionally depends on the location of the computer device 110 at the time the URL was received. The location can be determined using methods known from the prior art, for example, using coordinates obtained from global positioning systems (GPS, GLONASS, etc.), using Wi-Fi networks, cellular towers data, etc.

In general, the unique identifier of transmitter 120 may vary. Therefore, the transmitter 120 can be identified by its location (with a given accuracy), which was determined by the application 111 at the time of receiving the URL from this transmitter 120. Therefore, for example, even if the computer device 110 received two identical URLs from different transmitters 120, but their location coincides with a given accuracy (for example, 10 meters), then in this case we can assume that it was the same transmitter 120.

The level of publicity of the URL may depend on the location of the computer device 110. For example, the coordinates can be divided into several zones. If the location of the computer device 110 at the time the URL was received was, for example, in the first zone, the level of publicity may be higher than when the location of the device 110 is in another zone.

An example of determining the level of fame depending on the location is given in table 1. For example, for URL1 located in zone 1, the level of fame will be 5, and for URL1 located in zone 2, the fame will be 4. Thus, in this case transmitter 120 may be identified by a pair of URLs and a location. Moreover, even if two physically different transmitters 120 correspond to one pair of URLs and locations, they will be considered as one transmitter 120, because in terms of how to determine the level of trust in the URL, this is not important. The specific values of the fame level for different zones can be determined using the parameter base 140. For example, if for one URL1 there are more records in zone 1 than in zone 2, then the level of fame for zone 1 will be higher than for zone 2.

In one particular embodiment, the level of publicity of the obtained URL additionally depends on the level of publicity of other URLs obtained by the application 111 installed on at least one computer device 110. For example, if the level of publicity of neighboring URLs (whose communication with the URL in question exceeds a given value (for example , 0.3)) above a certain value (for example, 6), then the popularity level of the URL in question can be increased by one and the level of confidence in the URL will change accordingly. Thus, if the fame level for the first URL is higher than the fame level for the second URL, then the specified level of trust in the first URL will be equal to or higher than the level of confidence in the second URL.

In FIG. 2 shows an example of a computer device interacting with transmitters. As part of the example, the parameter database 140 contains URL1-URL3 and their corresponding fame levels (P), as well as communication power (M) for each pair of URLs.

Tables 2, 3 give an example of the possible values of the level of fame and communication power for each URL and URL pairs, respectively.

This information is presented in FIG. 2 in the form of a graph, where URLs are located at the vertices of the graph, and the edges of the graph correspond to the communication powers between the two URLs.

Thus, if the user device 110 receives a new URL4 from the transmitter 120 that is not in the parameter database 140, then the remote server 130 will determine the URL4 fame level equal to one, because URL4 was previously missing from the database. In this example, the user device 110 could also receive URL3 before or after receiving URL4 for a certain period of time, and thus, the communication power between URL3 and URL4 will not be zero, however, the communication power value will be small, for example 0.001. The communication power between URL4 and URL1-URL2 is zero, because these two pairs of URLs were not "met" at the same time by any computer device 110.

As mentioned earlier, the power of linking a URL to itself can also take real values. For example, the power of linking a URL with itself to accept a minimum or maximum value.

In addition, Table 2 shows the dependence of the level of trust in the URL on its level of fame and the power of communication between the given URL and other URLs (including with itself). The confidence levels of all URL1-URL3 are equal to one, which means that these URLs are considered known (trusted). Thus, the confidence level of URL4 will be zero, since the level of popularity of URL4 takes the minimum value (1), and the communication power does not exceed the specified value (for example, 0.3). On the graph, vertices in the form of a hollow circle correspond to URLs with a confidence level of one. The top of the graph in the form of a shaded circle corresponds to a confidence level of zero, which means that such a URL is probably fraudulent.

In one particular embodiment, the dependence of the level of trust in the URL on its level of fame and the power of communication between the given URL and other URLs can be adjusted using the parameter database 140. For example, a training sample of records containing two groups can be taken from parameter database 140 - URLs that are known to be trusted, and URLs that are known to be fraudulent. Information on trusted and fraudulent URLs can be obtained using expert systems of a remote server, for example, using the expert opinion of anti-virus analysts, by using additional anti-virus scanning of the content at the URLs indicated using the anti-virus tool mentioned above, using white lists, etc. d.

Further, each URL from a trusted group can be assigned a high value of the level of trust (for example, from 8 to 10), and each URL from a fraudulent group can be set to a low value of the level of trust (for example, from 1 to 2). Different values of two URLs from the same group can be set based on the following considerations. The first URL can be set to trust level 10 if it is in the white lists, and the second URL can be set to trust level 9 if the analyst considers the URL to be trusted, but it is not in the white lists, i.e. is lesser known. As a result, to determine the best dependence of the level of trust in the URL on the level of its popularity and the power of linking the URL with other URLs, classification algorithms on the training set can be used. Such algorithms can be, for example, the support vector method or the Bayesian classifier, in which the classification objects are URLs (or URLs and location, if location is used), and classification criteria are the level of popularity of the URL and the link strength of the specified URL with other URLs (i.e. hours with yourself). Using the classification, the optimal dependence can be determined in which the objects from the training set fall into the group corresponding to them - trusted URLs or fraudulent ones. In another particular embodiment, a test subsample can be taken from the training set, on which the obtained dependence will be checked, and if it does not give the best results, another classification algorithm can be used that gives the best classification result on the test set.

In FIG. Figure 3 shows a method of carrying out the invention, namely, a method for determining the level of confidence of a URL received from a transmitter, a device that broadcasts said URL over a wireless communication channel. In step 301, the application 111 receives the URL from the transmitter 120. Next, in step 302, the application 111 transmits the received URL and URL parameters to the remote server 130, which contain the date and time the application 111 received the URL, a unique identifier for the computer device 110 (for example, the MAC address).

At step 303, the remote server 130 stores the received URL and the obtained parameters into the parameter database 140, which contains at least one URL and the parameters of this URL. At step 304, the remote server 130 assigns the fame URL to the received URL — a parameter whose value depends on the number of computer devices 110 that received and transmitted the specified URL.

At step 305, the remote server 130 for the received URL and at least one other URL from the parameter base 140 assigns communication power — a parameter whose value depends on the parameters of both URLs and the number of events when both of the mentioned URLs were received by the same computer device in for a given period of time. At step 306, the remote server 130 stores for the received URL the assigned level of fame and power of communication with other URLs from the parameter database 140.

As a result, at step 307, the remote server 130 determines the level of trust in the received URL depending on the level of popularity and communication power with other URLs from the parameter database 140. At step 308, the remote server 130 transfers a certain level of trust of the received URL to the application 111 installed on the computer device 120. And at step 309, the computer device 120 through the application 111 controls access to an information resource on the network at the specified URL depending on a certain level of trust in the mentioned URL. Due to the implementation of the described method, the security of the computer device 110 will be improved and, in addition, the indicated technical problem is solved in determining the level of trust of the URL received from the transmitter and intended to restrict access to the URL.

Thus, the first technical result is achieved, which consists in improving the security of a computer device by controlling access to an information resource on the network depending on a certain level of trust for the URL that was received from the transmitter over a wireless communication channel. In addition, the second technical result is also achieved, because using the described method allows you to expand the arsenal of technical means for determining the level of trust for the URL that was received from the transmitter, with subsequent control of access to the information resource using the specified level of trust URL.

Particular embodiments of the method of the invention have been given previously, in the description of FIG. one.

FIG. 4 is an example of a general purpose computer system, a personal computer or server 20 comprising a central processor 21, a system memory 22, and a system bus 23 that contains various system components, including memory associated with the central processor 21. The system bus 23 is implemented as any prior art bus structure comprising, in turn, a bus memory or a bus memory controller, a peripheral bus and a local bus that is capable of interacting with any other bus architecture. The system memory contains read-only memory (ROM) 24, random access memory (RAM) 25. The main input / output system (BIOS) 26 contains the basic procedures that ensure the transfer of information between the elements of the personal computer 20, for example, at the time of loading the operating system using ROM 24.

The personal computer 20 in turn contains a hard disk 27 for reading and writing data, a magnetic disk drive 28 for reading and writing to removable magnetic disks 29, and an optical drive 30 for reading and writing to removable optical disks 31, such as a CD-ROM, DVD -ROM and other optical information carriers. The hard disk 27, the magnetic disk drive 28, the optical drive 30 are connected to the system bus 23 through the interface of the hard disk 32, the interface of the magnetic disks 33 and the interface of the optical drive 34, respectively. Drives and associated computer storage media are non-volatile means of storing computer instructions, data structures, software modules and other data of a personal computer 20.

The present description discloses an implementation of a system that uses a hard disk 27, a removable magnetic disk 29, and a removable optical disk 31, but it should be understood that other types of computer storage media 56 that can store data in a form readable by a computer (solid state drives, flash memory cards, digital disks, random access memory (RAM), etc.) that are connected to the system bus 23 through the controller 55.

Computer 20 has a file system 36 where the recorded operating system 35 is stored, as well as additional software applications 37, other program modules 38, and program data 39.
