[2. Basic concept of reliability evaluation]
Next, the basic concept of evaluating the reliability of the association between the first identification information and the second identification information in the present embodiment will be described with reference to FIG. 7.

In the present embodiment, the matching server 50 specifies the combination of the device ID and the cookie ID by associating the device ID and the cookie ID corresponding to the same IP address. Then, the matching server 50 evaluates reliability, which is a degree indicating that the device ID and the cookie ID related to the specified combination are information about the same individual or group. It is assumed that the higher the reliability, the higher the possibility that the device ID and the cookie ID related to the specified combination are information about the same individual or group.

Here, when a certain device ID and a cookie ID are information about the same individual / group, for example, the content output device 10 related to the device ID and the information device 20 related to the cookie ID are the same individual (user). ) / When it is owned by a group. The same group includes a group consisting of residents of a plurality of households living in a condominium or the like, a group consisting of members of an organization such as a company or an incorporated association, and the like.

In the present embodiment, reliability is comprehensively evaluated based on the following four criteria, that is, the first criterion, the second criterion, the third criterion, and the fourth criterion.
(1) First Criteria The first criterion is the number of first identification information (device ID in this embodiment) corresponding to the same network identification information (same IP address in this embodiment). Here, in a condominium or other condominium or a building owned by an organization (for example, a company, an incorporated association, etc.), a large number of content output devices 10 exist, and the large number of content output devices 10 communicate with one IP address. May be done. Further, even in the case of a detached house having a plurality of TVs, the plurality of TVs may communicate with one IP address. Therefore, the first standard tends to be larger in an apartment house, a building owned by an organization, or a detached house having a plurality of TVs. Conversely, with some exceptions such as a detached house with a large number of TVs, the smaller the first criterion, the more likely the combination of the device ID and cookie ID is information about the household living in the detached house. it is conceivable that. Further, it is considered that the larger the first criterion is, the higher the probability that the combination of the device ID and the cookie ID is a combination relating to a plurality of households or organizations living in an apartment house.
(2) Second Criteria The second criterion is the number of second identification information (cookie ID in this embodiment) corresponding to the same network identification information (IP address in this embodiment). In an apartment house or a building owned by an organization, information devices 20 (that is, many browsers) owned by a large number of people across multiple households or a large number of people belonging to the organization may communicate with one IP address. is there. Further, even in the case of a detached house having a plurality of browsers (that is, a plurality of information devices 20), the plurality of information devices 20 may communicate with one IP address. Therefore, the second standard tends to be larger in an apartment house, a building owned by an organization, or a detached house having a plurality of information devices 20. Conversely, with some exceptions such as a detached house with a very large number of information devices 20, the smaller the second criterion, the more the combination of device ID and cookie ID related to the IP address resides in the detached house. It is highly probable that the information is about the household. Further, it is considered that the larger the second criterion is, the higher the probability that the combination of the device ID and the cookie ID related to the IP address is a combination related to a plurality of households living in an apartment house or an organization such as a company.
(3) Third Criteria The third criterion is the number of network identification information (IP address in the present embodiment) corresponding to the same first identification information (same device ID in the present embodiment). The third criterion becomes large, for example, when the content output device 10 related to the device ID is connected to the mobile router. The third criterion is increased when the content output device 10 related to the device ID connects to the Internet via an Internet provider whose IP address is frequently changed.
(4) Fourth Criteria The fourth criterion is the number of network identification information (IP address in this embodiment) corresponding to the same second identification information (the same number of cookie IDs in this embodiment). The fourth criterion is increased, for example, when the information device 20 related to the cookie ID is a mobile information terminal. That is, when a user connects to the Internet via the information device 20 at a plurality of destinations, a plurality of IP addresses can be associated with the same cookie ID, so that the fourth criterion can be increased.

In the present embodiment, the matching server 50 evaluates the reliability that the specified combination is information about the same individual or group based on the above-mentioned first to fourth criteria. The smaller the values of all the criteria of the first to fourth criteria, the smaller the number of cookie IDs corresponding to one device ID, and the smaller the number of device IDs corresponding to one cookie ID. That is, the smaller the values of all the criteria of the first to fourth criteria, the closer the correspondence between the device ID and the cookie ID is to one-to-one correspondence. Therefore, it can be said that the smaller the values of all the criteria of the first to fourth criteria, the higher the reliability of the association.

[3. processing]
Next, the reliability evaluation process executed by the control unit 54 of the matching server 50 will be described with reference to the flowchart of FIG. The timing of executing the reliability evaluation process may be periodic (for example, every hour, every day, etc.), or may be any timing.

First, in S101, the control unit 54 acquires the first specific information for the past predetermined period (for example, the past X days) from the viewing log DB 52.

Subsequently, in S102, the control unit 54 acquires the second specific information for the past predetermined period (for example, the past X days) from the browsing log DB 53.

Subsequently, in S103, the control unit 54 associates the device ID and the cookie ID with the same IP address. Specifically, the control unit 54 determines (that is, matches) whether or not the IP address of the content output device 10 and the IP address of the information device 20 are the same. Then, when both IP addresses are the same, the control unit 54 stores the combination of the IP address, the corresponding device ID, and the corresponding cookie ID as shown in FIG.

Further, in S103, the control unit 54 determines whether or not the device ID and the cookie ID are acquired on the same day based on the time stamp attached to the viewing log of the content output device 10 and the time stamp attached to the cookie ID. Is determined, and the device ID and cookie ID acquired on the same day are linked. The method of linking the device ID and the cookie ID is not limited to this. For example, the device ID and the cookie ID whose time difference between the time when the device ID is acquired and the time when the cookie ID is acquired is equal to or less than a predetermined value are linked. You may attach it.

Subsequently, in S104, the control unit 54 acquires the correspondence information, and has the location and / or the device of the device represented by the IP address for each of the IP addresses related to one or more combinations specified in S103. Identify the organization to do.

That is, when a device such as the content output device 10 or the information device 20 accesses the Internet, it is possible to identify the location of the device and / or the organization that owns the device from the IP address of the source. The control unit 54 acquires correspondence information, which is information indicating a correspondence relationship between the IP address, the location information of the device represented by the IP address, and / or the organization information represented by the IP address. The correspondence information includes, for example, information on the prefecture or city where the device is located, information on the address of the organization that owns the device, and the like as information on the location of the device represented by the IP address. In addition, the correspondence information includes, for example, information such as a company name, an address, a latitude / longitude, and a telephone number as information on an organization that owns a device represented by an IP address. Correspondence information is published on the Internet by specialized vendors. The control unit 54 may acquire correspondence information by accessing the Internet via, for example, the communication unit 51. Further, for example, the correspondence information may be stored in advance in a database (not shown) included in the matching server 50, and the correspondence information may be acquired from the database.

Subsequently, in S105, the control unit 54 determines whether or not the location and / or the organization that owns the device represented by the IP address specified in S104 is the specific location and / or organization. In the present embodiment, the location of a building other than a detached house such as a building such as a condominium, a company, an incorporated association, a government office, a hospital, or a broadcasting station is assumed as a specific location. Similarly, a specific organization is assumed to be an organization other than a household of a detached house such as a condominium, a company, an incorporated association, a government office, a hospital, or a broadcasting station.

Subsequently, in S106, the control unit 54 excludes (that is, filters) the combination data related to the IP address for which the corresponding location and / or organization is determined to be a specific location and / or organization. To do. Here, when the location of the device represented by the IP address is the location of a building other than a detached house, the combination data related to the IP address is excluded for the following reasons. That is, since the reliability evaluation process of the present embodiment is a process of evaluating the reliability of the combination of the specified device ID and the cookie ID for the household living in the same detached house. Is. Of course, for example, when it is desired to evaluate the reliability that the specified combination is a combination of a device ID and a cookie ID related to an organization such as a condominium or an organization such as a company, for example, the condominium is set as a specific location related to S105. The location of a building that does not correspond to a company or a company (for example, the location of a residential area) may be set.

In the present embodiment, for the combinations excluded in S106, the processing after S107 (that is, the evaluation of reliability) is not performed. In addition, instead of or in addition to this, the excluded combinations may be controlled so that the advertisement distribution based on the viewing log is not performed.

Subsequently, in S107, the control unit 54 acquires the communication carrier IP address information. The communication carrier IP address information is information indicating an IP address used by one or more communication carriers. The communication carrier IP address information is, for example, a list of IP addresses used by the communication carrier. The IP address used by the communication carrier is open to the public on the Internet. The control unit 54 may acquire the communication carrier IP address information by accessing the Internet via the communication unit 51, for example. Further, for example, the communication carrier IP address information may be stored in advance in a database (not shown) included in the matching server 50, and the communication carrier IP address information may be acquired from the database.

Subsequently, in S108, the control unit 54 uses the IP address indicated by the communication carrier IP address information for each of the IP addresses related to the combination of the device ID and the cookie ID that remain without being excluded in S106. Determine if it exists. The IP address indicated by the communication carrier IP address information referred to here is, in other words, an IP address used by the communication carrier.

Subsequently, in S109, the control unit 54 excludes (that is, filters) the combination data related to the IP address determined to be the IP address indicated by the communication carrier IP address information in S108. That is, when the information device 20 makes an Internet connection using mobile data communication, the IP address of the communication carrier is assigned to the information device 20. At this time, a different IP address is assigned to the information device 20 each time it is connected to the Internet. Therefore, even if the device ID and the cookie ID are linked using such an IP address, it is difficult to link the device ID and the cookie ID with respect to the same individual or group with high reliability. Therefore, in the present embodiment, the combination data related to the IP address used by the communication carrier is excluded.

In the present embodiment, for the combinations excluded in S109, the processing after S110 (that is, the evaluation of reliability) is not performed. In addition, instead of or in addition to this, the excluded combinations may be controlled so that the advertisement distribution based on the viewing log is not performed.

Subsequently, in S110, the control unit 54 calculates the number of device IDs (that is, the first reference) corresponding to the IP address related to the combination of the specified device ID and the cookie ID. Here, the control unit 54 calculates the number of device IDs for each IP address on a daily basis for each day of the past predetermined period (past X days). Then, the maximum number of device IDs in the past predetermined period for each IP address is calculated as the first reference for the combination.

Subsequently, in S111, the control unit 54 calculates the number of cookie IDs (that is, the second reference) corresponding to the IP address related to each of the specified combinations of device IDs and cookie IDs. Here, the control unit 54 calculates the number of cookie IDs for each IP address on a daily basis for each day of the past predetermined period (past X days). Then, the maximum number of cookie IDs in the past predetermined period for each IP address is calculated as the second reference for the combination.

Subsequently, in S112, the control unit 54 calculates the number of IP addresses (that is, the third reference) corresponding to the device ID related to the combination of the specified device ID and the cookie ID. Here, the control unit 54 calculates the number of IP addresses for each device ID on a daily basis for each day of the past predetermined period (past X days). Then, the maximum number of IP addresses in the past predetermined period for each device ID is calculated as the third reference related to the combination.

Subsequently, in S113, the control unit 54 calculates the number of IP addresses (that is, the fourth criterion) corresponding to the cookie ID related to the combination of the specified device ID and the cookie ID. Here, the control unit 54 calculates the number of IP addresses for each cookie ID on a daily basis for each day of the past predetermined period (past X days). Then, the maximum number of IP addresses in the past predetermined period for each cookie ID is calculated as the third criterion related to the combination.

Subsequently, in S114, the control unit 54 evaluates the reliability level of each combination of the device ID and the cookie ID based on the first to fourth criteria calculated in S110 to S114, respectively. The reliability level here is the degree to which the reliability that the device ID and the cookie ID related to the specified combination are information about the same individual or group is divided into a plurality of stages. The higher the reliability level, the higher the reliability. The control unit 54 evaluates the reliability level of each combination based on the reliability level definition table as shown in FIG. In the definition table shown in FIG. 10, the higher the reliability level of the combination, the higher the probability that the device ID and the cookie ID related to the combination are information about the household living in the detached house.

Specifically, FIG. 10 shows a reliability level definition table that evaluates reliability in three levels of reliability (reliability levels 1 to 3). Then, for each of the reliability levels 1 to 3, threshold values of the values of the first to fourth reference values are set. That is, when all of the values of the first to fourth criteria of the specified combination are equal to or less than the thresholds of the first to fourth criteria of a certain reliability level (for example, reliability level 2). In addition, the reliability level of the combination corresponds to the certain level (for example, reliability level 2). In addition, one combination may correspond to a plurality of reliability levels (for example, reliability levels 1 and 2). In that case, the reliability level of the one combination can be determined to be the highest reliability level (for example, reliability level 2) among the plurality of applicable reliability levels. In FIG. 10, "Inf." Means infinity (infinity).

In the definition table shown in FIG. 10, the higher the reliability level, the same or smaller the threshold values of the first to fourth criteria. Further, the higher the reliability level of the combination, the smaller the number of cookie IDs corresponding to one device ID and the number of device IDs corresponding to one cookie ID, resulting in a more reliable combination. In particular, the higher the reliability level of the combination, the lower the first standard and the second reference value, so that the probability that the device ID and the cookie ID related to the combination are information about the household living in the detached house is high. The reliability level is determined by the number of content output devices 10 and the number of cookie IDs related to the combination corresponding to each reliability level, and the value obtained by dividing the number of cookie IDs by the number of content output devices 10. The higher it is, the less it is generally.

Note that the threshold values of the first to fourth criteria of each reliability level may be set based on the following ideas. That is, the number of device IDs (that is, the number of content output devices 10), the number of cookie IDs (that is, the number of information devices 20), and the number of IP addresses related to the combination corresponding to each reliability level are within the desired ranges. Set. For example, taking the threshold value of the first reference for each reliability level as an example, as shown in FIG. 11, when the first reference value is in the range of 1 to 5, the cumulative number of corresponding IP addresses changes. Can be seen. In other words, the first reference value is the number of content output devices 10 associated with one IP address. On the other hand, when the first reference value is 5 or later, the cumulative number of IP addresses does not change much. Therefore, if a threshold is set for the first criterion and the number of applicable combinations is to be reduced as the reliability level increases, the threshold for the first criterion is set within the range of 1 to 5. I know what to do. The threshold values of the second to fourth criteria may be set in the same manner. Of course, the threshold values of the first to fourth criteria may be set based on a concept different from the above.

The control unit 54 evaluates the reliability level of each combination of the device ID and the cookie ID as described above.

Subsequently, in S115, the control unit 54 classifies the combination of the device ID and the cookie ID based on the reliability level evaluated in S114. In the present embodiment, the control unit 54 classifies the combination determined to have the reliability level equal to or higher than the predetermined level as a combination of the device ID and the cookie ID related to the household living in the detached house. After that, the control unit 54 ends the reliability evaluation process of FIG.

[4. effect]
According to the embodiment described in detail above, the following effects can be obtained.

(1) In the present embodiment, the control unit 54 specifies a combination of a device ID and a cookie ID corresponding to the same IP address. Then, the control unit 54 evaluates the reliability level indicating that the device ID and the cookie ID related to the specified combination are information about the same individual or group based on the first criterion and the second criterion.

Therefore, the degree to which the device ID and the cookie ID related to the specified combination indicate that they are information about the same individual or group can be evaluated by a new method.

(2) In the present embodiment, the control unit 54 evaluates the reliability level based on the first criterion, the second criterion, and the third criterion. It is considered that the third criterion, that is, the smaller the number of IP addresses corresponding to the same device ID, the smaller the number of cookie IDs corresponding to the same device ID. That is, it is considered that the smaller the third criterion is, the smaller the number of cookie IDs corresponding to one device ID is, and the more reliable the association can be made. Therefore, for example, as compared with the case where the reliability level is evaluated only by the first criterion and the second criterion, the association is more reliable when the device ID and the cookie ID related to the same individual or group are associated. It can be performed.

(3) In the present embodiment, the control unit 54 evaluates the reliability level based on the first criterion, the second criterion, and the fourth criterion. It is considered that the fourth criterion, that is, the smaller the number of IP addresses corresponding to the same cookie ID, the smaller the device ID corresponding to the same cookie ID. That is, it is considered that the smaller the fourth criterion is, the smaller the number of device IDs corresponding to one cookie ID is, and the more reliable the association can be made. Therefore, for example, as compared with the case where the reliability level is evaluated only by the first criterion and the second criterion, the association is more reliable when the device ID and the cookie ID related to the same individual or group are associated. It can be performed.

(4) In the present embodiment, the control unit 54 evaluates the reliability level based on the first criterion, the second criterion, the third criterion, and the fourth criterion. Thus, for example, the reliability level relates to the same individual or group as compared to the case where the reliability level is evaluated by only one of the third criterion and the fourth criterion in addition to the first criterion and the second criterion. When linking the device ID and the cookie ID, more reliable linking can be performed.

(5) In the present embodiment, the control unit 54 acquires the correspondence information. Then, the control unit 54 excludes the IP address whose corresponding location and / or organization is determined to be a specific location and / or organization from the evaluation of the reliability level based on the acquired correspondence information. ..

Therefore, it is possible to easily extract only the combination of the device ID and the cookie ID, which have relatively high reliability, as compared with the case where the IP address corresponding to the location and / or the organization is not excluded.

(6) In the present embodiment, the control unit 54 excludes the IP address determined to be the IP address used by the communication carrier from the evaluation of the reliability level.

Therefore, it is possible to easily extract only the combination of the device ID and the cookie ID, which have relatively high reliability, as compared with the case where the IP address of the communication carrier is not excluded.

In the present embodiment, the matching server 50 corresponds to the information processing device, the device ID corresponds to the first specific information, the cookie ID corresponds to the second identification information, and the IP address corresponds to the network identification information. However, the reliability level corresponds to the degree, S101 and S102 correspond to the processing as the specific information acquisition unit, S103 corresponds to the processing as the specific unit, and S104 corresponds to the processing as the corresponding information acquisition unit. S105 and S106 correspond to the processing as the first exclusion processing unit, S108 and S109 correspond to the processing as the second exclusion processing unit, and S114 corresponds to the processing as the evaluation unit.

[5. Other embodiments]
Although the embodiment for carrying out the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment, and can be implemented in various modifications.

(1) In the above embodiment, the device ID of the content output device is illustrated as the first identification information, but the first identification information is not limited to this. The first identification information may be, for example, a user ID registered in the content output device or the like. That is, the first identification information may be information that can identify the user of the content output device. Further, for example, the first identification information may be identification information acquired by the content output device or the like via a network with the outside. In this case, for example, the order in which the content output device communicates with the external server and connects to the external server may be used as the first identification information.

(2) In the above embodiment, the cookie ID is exemplified as the second identification information, but the second identification information is not limited to this. For example, the second identification information may be an advertisement ID. The advertisement ID may be an anonymous and unique identifier for advertisement delivery (identifier related to the advertisement) that can be opt-out by the user. Further, for example, the second identification information may be the device ID of the information device, the user ID registered in the information device, or the like. That is, the second identification information may be information that can identify the user of the information device. Further, for example, the second identification information may be identification information acquired by an information device or the like via a network with the outside.

(3) In the above embodiment, the IP address indicating the location of the device on the Internet is exemplified as the network identification information, but the network identification information is not limited to this. The network identification information may be, for example, information indicating the location of other devices on the network. Other networks include, for example, wireless LAN, Bluetooth (Bluetooth) (registered trademark), RFID (Radio Frequency Identification), infrared communication (Infrared Data Association: IrDA) (registered trademark), UWB (Ultra Wideband) (registered trademark), etc. Examples include ZigBee (registered trademark).

(4) In the above embodiment, the content output device 10 and / or the information device 20 may be a video playback device having a function of reproducing video such as signage.

(5) The reliability level evaluation method (that is, the definition of the reliability level) in the above embodiment is just an example, and other definitions may be adopted. For example, a definition table other than the definition table shown in FIG. 10 may be used. In this case, for example, a definition table may be used in which the thresholds of the first criterion and the second criterion increase as the reliability level increases. According to this definition table, the higher the reliability level of the combination, the higher the probability that the device ID and the cookie ID related to the combination are information about an organization such as a plurality of households or companies living in the housing complex.

Further, the control unit 54 may use a plurality of reliability level definition tables in combination and evaluate a plurality of types of reliability levels for each combination.

(6) In the above embodiment, the control unit 54 may classify each combination into one of a plurality of classifications (groups) based on the evaluated reliability level. The classification referred to here is, for example, a group of combinations having a high probability of households living in a detached house, a group of combinations having a high probability of having a plurality of households living in an apartment house, and the like.

(7) In the above embodiment, the control unit 54 may evaluate the reliability level without being based on at least one of the third criterion and the fourth criterion.

(8) In the above embodiment, the reliability level may be evaluated in a plurality of stages other than the three stages.

(9) The method of calculating the reliability level is not limited to that of the above embodiment. For example, the reliability level of the combination is evaluated based on the sum, difference, product, quotient, etc. of the values of the first to fourth criteria of the specified combination of the first identification information and the second identification information. May be good. Also, for example, the reliability level of a combination may be evaluated based on the minimum or maximum value of the first reference value to the fourth reference value of the combination. Further, for example, as in the above embodiment, the reliability level is not calculated separately based on the values of the first to fourth criteria, but the combination specified by the values of the first to fourth criteria themselves. It may be a degree indicating that the first identification information and the second identification information according to the above are information about the same individual or group. That is, it is not necessary to calculate the three levels of reliability in the above embodiment. The same applies when the reliability level is evaluated not based on the four criteria of the first to fourth criteria but based on some criteria (for example, only the first and second criteria).

(10) In the above embodiment, the IP address related to the condominium, the company, etc. is excluded by using the correspondence information, but the usage of the IP address is not limited to this.

For example, the thresholds of the first to fourth criteria of the reliability level may be changed when the location and / or organization corresponding to the network identification information such as the IP address is a specific location and / or organization. ..

That is, the variation in the values of the first standard and the second standard changes depending on whether the location of the device indicated by the IP address is a residential area where many detached houses exist or an office area where many companies exist. Specifically, when the location is an office district, the number of content output devices 10 associated with one IP address tends to be larger than when the location is a residential district. Therefore, it is assumed that the relationship between the first reference value and the number of IP addresses (relationship as shown in FIG. 11) differs between the case where the location is an office district and the case where the location is a residential district. Will be done. Therefore, it is conceivable to change the threshold value in order to keep the number of content output devices 10 and the number of cookie IDs related to the number of combinations belonging to each reliability level within a desired range.

According to such a configuration, for example, when the location and / or organization corresponding to the network identification information such as the IP address is a specific location and / or organization, the first to fourth criteria of the reliability level are used. By changing the threshold value, the evaluation accuracy according to the reliability level can be improved.

(11) In the above embodiment, the control unit 54 acquires the contractor information related to the communication carrier of the user of the information device 20 related to the cookie ID from the communication carrier or the like, and uses the acquired contractor information for reliability. You may evaluate the level. The contractor information referred to here is, for example, information in which the second identification information of the information device 20 used by the user who is the contractor is associated with the user information including the name, age, gender, etc. of the user. is there. Further, for example, the contractor information includes the contract status of the user who is the contractor of the communication carrier and the communication carrier of another user in the same group, and the other when the other user has a contract with the communication carrier. The information may include the second identification information of the information device 20 used by the user. The same group referred to here is, for example, the same family or the same organization, and the contract status with a telecommunications carrier is, for example, whether or not a telecommunications carrier is contracted.

For example, it is assumed that one user (for example, a father) in a certain family can be associated with a high reliability level of the content output device 10 and the information device 20. In this case, for example, the control unit 54 contracts with the communication carrier for another user (for example, a daughter) of the family of the one user based on the contractor information relating to the communication carrier of the one user (for example, the father). Determine if it is. Then, when the control unit 54 determines that the other user (for example, a daughter) also has a contract with the communication carrier, the second user of the information device 20 of the other user is based on the contractor information of the other user. Acquire the identification information of. Then, the reliability level of the association between the acquired second identification information of the information device 20 of the other user and the content output device 10 in the family may be improved. That is, the control unit 54 may evaluate the reliability level based on the contractor information related to the communication carrier, separately from the first to fourth criteria. The reliability level may be evaluated not only for family members but also for a plurality of users in the same organization in the same manner as described above.

Further, for example, when a plurality of cookie IDs correspond to one device ID, the control unit 54 acquires the contractor information of the user of the information device 20 related to the linked cookie ID from a communication carrier or the like. Then, the control unit 54 acquires user information such as age and gender from the acquired contractor information, and extracts only the cookie ID related to the information device 20 having a desired user attribute based on the acquired user information. , The rest may be excluded.

Further, for example, when the IP address is the IP address used by the communication carrier, the variation in the values of the third reference and the fourth reference changes as compared with the case where the IP address is not the IP address used by the communication carrier. .. Therefore, in order to keep the number of content output devices 10 and the number of cookie IDs related to the combinations belonging to each reliability level within a desired range, the thresholds of the third criterion and the fourth criterion in the reliability level definition table. You may change the value.

According to such a configuration, the evaluation accuracy based on the reliability level can be improved as compared with the case where the reliability level is evaluated without using the contractor information of the user of the information device 20.

(12) In the above embodiment, the control unit 54 excludes (filters) the IP address in S106 and S108 after specifying the combination of the device ID and the cookie ID in S103. However, the timing of excluding IP addresses is not limited to this. For example, the IP address may be excluded before identifying the combination.

(13) In the above embodiment, for example, the first criterion may be calculated as an average value of the number of device IDs for each IP address over the past predetermined period. That is, the first criterion may be calculated by a method different from that of the above embodiment. The same applies to the second to fourth criteria.

(14) In the above embodiment, the first specific information does not have to include the viewing log related to the content output device 10. Further, the second specific information does not have to include a browsing log related to the information device 20.

(15) In the information processing system 1 of the above embodiment, the functions of a plurality of devices may be realized by one device. For example, the matching server 50, the viewing log management server 40, and the advertisement distribution server 60 may be implemented on one server.

(16) In the above embodiment, a part or all of the functions executed by the control unit 54 of the matching server 50 may be configured in hardware by one or more ICs or the like.

(17) In addition to the matching server 50 described above, an information processing system 1 having the matching server 50 as a component, a program for operating a computer as the matching server 50, a semiconductor memory storing this program, and the like are non-transitional. The present disclosure can also be realized in various forms such as a substantive storage medium and a method for evaluating the degree.

(18) A plurality of functions possessed by one component in the above embodiment may be realized by a plurality of components, or one function possessed by one component may be realized by a plurality of components. .. Further, a plurality of functions possessed by the plurality of components may be realized by one component, or one function realized by the plurality of components may be realized by one component. Further, a part of the configuration of the above embodiment may be omitted. In addition, at least a part of the configuration of the above embodiment may be added or replaced with the configuration of the other embodiment. It should be noted that all aspects included in the technical idea specified by the wording described in the claims are embodiments of the present disclosure.
