In an embodiment, the DSB is located in a public place, such as a retail store, a shopping complex, a stadium, a hotel, a corporate building, and/or the like. In an embodiment, the DSB is associated with one or more products and/or services that are in a proximity range of the DSB. In an embodiment, the DSB is utilized to display targeted content associated with the one or more products and/or services to a plurality of users when the plurality of users is within the proximity range of the DSB. In an embodiment, the DSB is integrated with an interactive user interface, such as a touch screen that allows the user to interact with the DSB.

A “proximity range” refers to a communication range associated with a device. In an embodiment, two devices may be able to communicate with each other only if they are within the proximity range of each other. In an embodiment, the proximity range of a device may depend on one or more sensors installed in the device for communication. In an embodiment, the device may correspond to a DSB, a user-computing device and/or the like. For example, a DSB with a proximity range of “200 ft” may detect the presence of a mobile phone that is within a radius of “200 ft” from the DSB.

“One or more products and/or services” refer to one or more commodities and/or facilities that may be required/utilized/availed by a user. In an embodiment, a user profile of the user may be maintained by a user-computing device associated with the user, based on one or more activities of the user related to the one or more products and/or services. In an embodiment, a DSB may be associated with the one or more products and/or services that are available within the proximity range of the DSB. Examples of the products may include groceries, watches, sports-equipment, jewelry, apparels, and/or the like. Examples of the services may include financial services, healthcare services, education services, and/or the like.

A “user profile” refers to the profile associated with a user that includes one or more preferences of the user towards one or more products and/or services. In an embodiment, the user profile of the user may further comprise a static user profile and a dynamic user profile. The static user profile includes one or more of: demographic attributes (such as age, gender, and/or the like), sports-related activities (such as average time of cycling, indoor sports preference, and/or the like), and health-related information (such as height, weight, blood group and/or the like) of the user. The dynamic profile includes one or more activities of the user related to the one or more products and/or services. Further, a weight is assigned to each of the one or more products and/or services in the dynamic profile, based on the activities of the user related to the one or more products and/or services.

“One or more activities” of a user refers to one or more actions of a user related to one or more products and/or services. In an embodiment, the one or more activities may include purchasing a product, availing a service, showing interest in the product and/or the service on a website and/or the like.

“Targeted content” refers to specific content that may be of interest to a user. In an embodiment, the targeted content may be determined, based on a user profile of the user. In an embodiment, the targeted content may be associated with consolidated preferences, such as an aggregated encrypted profile, of more than one users. In an embodiment, the targeted content may be rendered on a DSB. Examples of the targeted content may include, but are not limited to, advertisements, offers, discounts, and/or coupons.

“Encryption” refers to a process of encoding content using one or more encryption algorithms. The encryption process generates a cipher-text of the content that can only be read when decrypted. In an embodiment, a user may require an encryption key to encrypt the content.

“Decryption” refers to a process of converting encrypted content into content that can be read and understood by a user. In an embodiment, the user may require a decryption key to decrypt the encrypted content.

A “weight” corresponds to a measure of likelihood associated with one or more activities of a user related to one or more products and/or services. In an embodiment, the weight is indicative of the likelihood of the user to purchase the one or more products and/or avail the one or more services.

A “set of rules” refers to one or more conditions based on which two or more products and/or services are associated with each other.

In an alternate embodiment, the DSB 104 may transmit the information pertaining to the identification codes, such as the Xpath expressions, of the associated products and/or services, in the metadata, to the user-computing device 102A.

After the extraction/reception of the information pertaining to identification codes of the one or more products and/or services, the first processor 202 may be configured to select the profile information from the user profile. For example, the first processor 202 may be configured to match the Xpath expressions of the products and/or services with the XML format of the products and/or services in the user profile. Thereafter, based on the match between the Xpath expressions and the XML format the first processor 202 may select the profile information from the user profile.

In an embodiment, the encrypted profile information may further comprise encrypted static profile information and encrypted dynamic profile information. Thereafter, the first transceiver 206 in each of the plurality of user-computing devices 102 may be configured to transmit the selected encrypted profile to the server 108.

Thereafter, the third transceiver 406 may be configured to receive the selected encrypted profile information from each of the plurality of user-computing devices 102. In an embodiment, the received encrypted profile information from each of the plurality of user-computing devices 102 may be associated with the unique identification of the DSB 104 that transmitted the metadata to each of the plurality of user-computing devices 102.

At step 606, the encrypted profile information received from each of the plurality of user-computing devices 102 is aggregated. In an embodiment, the aggregation unit 408, in conjunction with the third processor 402, may be configured to aggregate the encrypted profile information received from each of the plurality of user-computing devices 102. In an embodiment, the aggregation unit 408 may utilize the one or more aggregation techniques known in the art for the aggregation of the encrypted profile information received from each of the plurality of user-computing devices 102. Examples of the one or more aggregation techniques may include, but not limited to, homomorphic aggregation and/or binary aggregation. In an embodiment, for aggregating the encrypted profile information received from each of the plurality of user-computing devices 102, the aggregation unit 408 may utilize equation 2, as shown below:

C=E _PK(P_A+P_B+P_C+ . . . P_N)  (2)

where,

E_PK represents an encryption key, such as the public key of the service provider;

P_A, P_B, P_C, . . . , P_N represents the profile information selected from each of the plurality of user-computing devices; and

C represents the aggregated encrypted profile.

For example, the aggregation unit 408 may aggregate the encrypted profile information, such as “C_A” (i.e., “E_PK (P_A)”), “C_B” (i.e., “E_PK (P_B)”), “C_C” (i.e., “E_PK (P_C)”), and “C_E” (i.e., “E_PK (P_E)”), received from each of the plurality of user-computing devices 102 to generate the aggregated encrypted profile, such as “C” (i.e., “E_PK (P_A+P_B+P_C+P_E)”).

In an embodiment, the aggregation unit 408 may be configured to aggregate the encrypted static profile information from each of the plurality of user-computing devices 102 by utilizing a binary aggregation technique. For example, the encrypted static profile information from the user-computing device 102A may be “SP₁” and the encrypted static profile information from the user-computing device 102B may be “SP₂” (i.e., SP₁={1, 0, 0, 1, 1, 0, 1} and SP₂={1, 1, 0, 0, 1, 0, 0}). The aggregation unit 408 may perform an “OR” operation on the received encrypted static profile information from the user-computing device 102A and the user-computing device 102B. Thus, the aggregated encrypted static profile may be SP_a={1, 1, 0, 1, 1, 0, 1}.

In an embodiment, the aggregation unit 408 may be further configured to aggregate the encrypted dynamic profile information from each of the plurality of user-computing devices 102 based on the weight of each node in the encrypted dynamic profile information. For example, corresponding to products, such as “watches,” “smartphones,” “groceries” and “sports equipment,” the weights in the encrypted dynamic profile from the user-computing device 102A may be “DP₁” and the weights in the encrypted dynamic profile from the user-computing device 102B may be “DP₂” such that DP₁={0.67, 0.34, 0.24, 0.89} and DP₂={0.37, 0.94, 0.14, 0.79}. In this scenario, the aggregation unit 408 may utilize the one or more aggregation algorithms to generate the aggregated encrypted dynamic profile as DP_a={0.52, 0.64, 0.19, 0.84}.

In an embodiment, the aggregated encrypted profile may be a combination of the aggregated encrypted static profile and the aggregated encrypted dynamic profile. For example, the aggregated encrypted profile “C” may be a combination of the aggregated encrypted static profile “SP_a” and the aggregated encrypted dynamic profile “DP_a” (i.e., C={{1, 1, 0, 1, 1, 0, 1}, {0.52, 0.64, 0.19, 0.84}}.

In an embodiment, the aggregation unit 408 may aggregate the encrypted profile information, received from each of the plurality of user-computing devices 102, based on the unique identification of the DSB 104 that is associated with the encrypted profile information. For example, the third transceiver 406 may receive the encrypted profile information from four user-computing devices, such as user-computing devices 102A to 102D. The encrypted profile information from the user-computing devices 102A and 102D may be associated with the unique identification, such as “DSB_1,” and the encrypted profile information from the user-computing devices 102B and 102C may be associated with the unique identification, such as “DSB_2.” In this scenario, the aggregation unit 408 may aggregate the encrypted profile information from the user-computing devices 102A and 102D to generate the aggregated encrypted profile “C₁.” Further, the aggregation unit 408 may aggregate the encrypted profile information from the user-computing devices 102B and 102C to generate the aggregated encrypted profile “C₂.”

A person having ordinary skill in the art will understand that the scope of the abovementioned example is for illustrative and should not be construed to limit the scope of the disclosure.

At step 608, the aggregated encrypted profile is transmitted to the content server 110. In an embodiment, the third transceiver 406, in conjunction with the third processor 402, may be configured to transmit the aggregated encrypted profile to the content server 110, over the network 112. The content server 110 may be configured to receive the aggregated encrypted profile and decrypt the aggregated encrypted profile. In an embodiment, based on the decrypted aggregated profile, the content server 110 may be configured to select the targeted content. Further, the selected targeted content may be displayed on the DSB 104. Control passes to the end step 610.

The method to decrypt the aggregated encrypted profile for the selection of the targeted content has been explained later in FIG. 7.

FIG. 7 depicts a flowchart that illustrates a method for displaying targeted content on a DSB, in accordance with at least one embodiment. FIG. 7 is described in conjunction with FIGS. 1-6. With reference to FIG. 7, there is shown a flowchart 700 that illustrates the method for displaying the targeted content on the DSB 104 by the content server 110. The method starts at step 702 and proceeds to step 704.

At step 704, the aggregated encrypted profile from the server 108 is received. In an embodiment, the fourth transceiver 506, in conjunction with the fourth processor 502, may be configured to receive the aggregated encrypted profile from the server 108, over the network 112. Prior to the reception of the aggregated encrypted profile, the server 108 may be configured to generate the aggregated encrypted profile, based on the selected encrypted profile information received from each of the plurality of user-computing devices 102. The selection of the encrypted profile information and the aggregation of the selected encrypted profile information have been explained in steps 604 and 606, respectively, of FIG. 6.

At step 706, the aggregated encrypted profile is decrypted to select the targeted content, from the content repository 510, associated with the one or more products and/or services. In an embodiment, the decryption unit 508, in conjunction with the fourth processor 502, may be configured to decrypt the aggregated encrypted profile. In an embodiment, the decryption unit 508 may utilize the one or more decryption algorithms (known in the art) for the decryption of the aggregated encrypted profile. In an embodiment, the decryption unit 508 may use a decryption algorithm that is compatible with the encryption algorithm, utilized by the encryption unit 208, to decrypt the aggregated encrypted profile. In an embodiment, for decrypting the aggregated encrypted profile, the decryption unit 508 may utilize equation 3, as shown below:

P=D _SK(C)  (3)

where,

C represents the aggregated encrypted profile;

D_SK represents a decryption key, such as the private key of the service provider; and

P represents the decrypted aggregated profile.

For example, the encryption unit 208 may encrypt the profile information by utilizing a public key, such as “E_PK,” of a service provider. In this scenario, the decryption unit 508 may utilize a private key, such as “D_SK,” of the service provider to decrypt the aggregated encrypted profile. In an embodiment, the decrypted aggregated profile may represent aggregated preferences of the users, towards the one or more products and/or services, associated with the plurality of user-computing devices 102.

After the decryption of the aggregated encrypted profile, the fourth processor 502 may utilize the decrypted aggregated profile to select the targeted content from the content repository 510. In an embodiment, the selected targeted content may be associated with the one or more products and/or services that are associated with the decrypted aggregated profile. In an embodiment, the selected targeted content may include one or more advertisements, offers, discounts, and/or coupons associated with the one or more products and/or services.

For example, the decrypted aggregated profile may be associated with four products, such as “watches,” “smartphones,” “groceries,” and “sports equipment,” and two services, such as “healthcare” and “finance.” Further, the content repository 510 may comprise content pertaining to five products, such as “watches,” “smartphones,” “groceries,” “sports equipment,” “animal and pet supplies,” and “clothing” and three services, such as “education,” “healthcare,” and “finance.” Thus, the fourth processor 502 may select the content associated with the products, such as “watches,” “smartphones,” “groceries,” and “sports equipment,” and the services, such as “healthcare” and “finance” from the content repository 510. The selected content corresponds to the targeted content.

In another embodiment, the fourth processor 502 may further select the targeted content, based on a profitability factor associated with the targeted content and/or a pre-specified count. In an embodiment, the profitability factor may be determined, based on a difference between a cost associated with the content and revenue generated by the content. In an embodiment, the fourth processor 502 may select a pre-specified count of the targeted content that has the maximum profitability factor. For example, the pre-specified count may be “4.” The fourth processor 502 may select the content associated with the products, such as “watches,” “smartphones,” “groceries,” and “sports equipment,” and the services, such as “healthcare” and “finance.” The profitability factor associated with each of the selected content may be “watches: 30%,” “smartphones: 33%,” “groceries: 60%,” “sports equipment: 73%,” “healthcare: 67%” and “finance: 42%.” In this scenario, the fourth processor 502 may select “sports equipment,” “healthcare,” “groceries,” and “finance” as the targeted content, based on the pre-specified count “4” and the profitability factor.

A person having ordinary skill in the art will understand that the scope of the abovementioned example is for illustrative purpose and should not be construed to limit the scope of the disclosure.

At step 708, the selected targeted content is rendered through a user-interface that is displayed on the DSB 104. In an embodiment, the fourth transceiver 506, in conjunction with the fourth processor 502, may be configured to render the selected targeted content through the user interface on the DSB 104. In an embodiment, the fourth transceiver 506 may be configured to transmit the selected targeted content to the DSB 104. After the reception of the targeted content, the second input/output unit 310 may display the received targeted content to a plurality of users associated with the plurality of user-computing devices 102. And the control passes to the end step 710.

FIGS. 8A and 8B collectively illustrates an exemplary scenario for displaying the targeted content on a DSB, in accordance with at least one embodiment. FIGS. 8A and 8B have been explained in conjunction with FIGS. 1-7. With reference to FIGS. 8A and 8B, there are shown exemplary scenarios 800a and 800b, respectively, for displaying the targeted content on the DSB 104.

The user-computing devices 102A, 102B, 102C and 102E of the plurality of user-computing devices 102 may be within the proximity range 114 of the DSB 104. The user-computing devices 102A, 102B, 102C and 102E may remain within the proximity range 114 for the pre-specified time interval (e.g., “15 seconds”). Further, other user-computing devices 102D and 102F of the plurality of user-computing devices 102 may be out of the proximity range 114 of the DSB 104. Thereafter, the DSB 104 may detect the presence of the user-computing devices 102A, 102B, 102C and 102E by utilizing one or more communication protocols, such as an NFC protocol. In an embodiment, the DSB 104 may not detect the presence of the other user-computing devices 102D and 102F. Further, the DSB 104 may transmit the metadata (transmission of the metadata is depicted by message flow step 802 in FIG. 8B) to each of the user-computing devices 102A, 102B, 102C and 102E within the proximity range 114 of the DSB 104. The DSB 104 may be associated with the one or more products and/or services, such as “watches,” “groceries,” “apparels” and “sports equipment,” such that the one or more products and/or services are available in one or more sections 106 (i.e., sections 106A, 106B, and 106C) that lie within the proximity range 114 of the DSB 104.

Based on the received metadata, each of the user-computing devices 102A, 102B, 102C and 102E selects the encrypted profile information, such as “C_A,” “C_B,” “C_C,” and “C_E,” from the encrypted user profile stored at each of the user-computing devices 102A, 102B, 102C and 102E. The encrypted profile information is selected from the user profile, based on the association of the DSB 104 with the one or more products and/or services. In an embodiment, each of the plurality of user-computing devices 102 may encrypt the user profile and the selected profile information (i.e., “P_A,” “P_B,” “P_C,” and “P_E”) by utilizing an encryption key, such as “E_PK,” based on equation 1, as expressed in FIG. 6. Thereafter, the encrypted profile information (i.e., “C_A,” “C_B,” “C_C,” and “C_E”) from corresponding user-computing devices 102A, 102B, 102C and 102E, is transmitted to the server 108 (transmission of the encrypted profile information is depicted by message flow step 804, in FIG. 8B). The server 108 may aggregate the encrypted profile information, received from each of the plurality of user-computing devices 102, to generate the aggregated encrypted profile, such as “C,” based on equation 2, as expressed in FIG. 6.

Thereafter, the server 108 may transmit the aggregated encrypted profile, such as “C,” to the content server 110 (transmission of the aggregated encrypted profile is depicted by message flow step 806 in FIG. 8B). The content server 110 may decrypt the received aggregated encrypted profile, such as “C.” In an embodiment, the content server 110 may decrypt the aggregated encrypted profile by utilizing a decryption key, such as “D_SK,” based on equation 3, as expressed in FIG. 6. Further, based on the decrypted aggregated profile, such as “P,” the content server 110 may select the targeted content from the content repository 510 in the content server 110. The selected targeted content is further associated with the one or more products and/or services (i.e., “watches,” “groceries,” “apparels” and “sports equipment”) that are associated with the DSB 104.

After the selection of the targeted content, the content server 110 may transmit the targeted content to the DSB 104 (transmission of the targeted content is depicted by message flow step 808 in FIG. 8B). The transmitted targeted content is rendered through the user interface that is displayed on the DSB 104. Each of the plurality of users associated with the plurality of user-computing devices 102 is able to view the targeted content displayed on the DSB 104.
