Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    Embodiments of the present invention generally relate to software provisioning, and more particularly, to a method and apparatus for provisioning subscription products. 
         [0003]    2. Description of the Related Art 
         [0004]    Provisioning is a process of preparing and equipping a product to allow it to provide new or updated services to a user entitled to have access to the product. A software subscription product is a product in which a user pays a subscription price in order to have access to the product for a specified duration or term, which term is generally renewable, but may be for an unlimited term. When a user purchases a software subscription product, the user typically enters a subscription serial number in order to gain access to the product. Software providers release new subscription applications and upgrades for access by entitled users. For example, an ADOBE® CREATIVE SUITE® 5.5 Suite subscription users may update to an ADOBE® CREATIVE SUITE® 6 Master Collection subscription or an ADOBE® CREATIVE CLOUD® subscription. Alternatively, an ADOBE® CREATIVE SUITE® 6 Photoshop subscription user may update to an ADOBE® CREATIVE CLOUD® subscription. 
         [0005]    Currently, in order to use a subscription product, a user must first register with a subscription provider and then enter a subscription serial number. The subscription serial number defines the user&#39;s entitlements for a specific product. The entitlements for a product are typically stored on the subscription provider&#39;s server as an object in a database. The subscription provider uses subscription object information in the database to auto-renew subscriptions. For example, a subscription object may contain information about the product to which a user is entitled and terms of the subscription. When a user wishes to upgrade to a newer version of a subscription product, the user must re-enter the subscription serial number the user received when the original subscription product was purchased. Unfortunately, a subscription serial number may be misplaced by the user or stolen and used by an unauthorized user. 
         [0006]    One solution is to issue new subscription serial numbers for product upgrades. However, the original product from which the subscription was upgraded would stop working because the original product is still associated with the previous subscription serial number. Also, auto-renewal of subscriptions would no longer work because the new subscription object in the subscription provider&#39;s database would override any older version of the subscription object. Updating the old subscription objects on the subscription provider&#39;s database is not feasible as the number of subscription objects would increase with each release or upgrade and managing them would soon become a formidable challenge. 
         [0007]    Therefore, there is a need for a method and apparatus for provisioning subscription products. 
       SUMMARY OF THE INVENTION 
       [0008]    Embodiments of the invention generally relate to a method and apparatus for provisioning subscription products. The method and apparatus comprise receiving a request for a subscription product. The method and apparatus retrieve a profile and at least one subscription associated with the profile, wherein the at least one subscription comprises a plurality of subscription details. The method and apparatus validate the plurality of subscription details and retrieve product data for the subscription product based on the validated subscription details. After determining a dominant subscription product if there are at least two subscriptions associated with the profile; the method and apparatus send the product data for the dominant subscription product, wherein the product data enables activation of a product license.

       DETAILED DESCRIPTION OF EMBODIMENTS 
       [0013]    Embodiments of the present invention comprise a method and apparatus for provisioning subscription products. Embodiments of the invention enable a user to sign-in to a subscription provider and use their new or upgraded subscription product. 
         [0014]    In one embodiment source provisioning table is stored on a subscription provider&#39;s server. The source provisioning table includes information that defines each subscription product and entitlements that are available to users for each subscription product. An entitlement is analogous to a user license. Thus, the source provisioning table includes a provisioning/renewal stock keeping unit (SKU), a serial number SKU, a numeric product version, and an installer scenario key for each subscription product. The provisioning/renewal SKU is a subscription SKU identifier for a product. Each SKU may have multiple serial number SKUs, for example, ADOBE® PHOTOSHOP® English will have a different serial number SKU than ADOBE® PHOTOSHOP® German, but both will have the same provisioning/renewal SKU. The numeric product version is an identifier that describes the version of the serial number SKU. The installer scenario key is a combination of three pieces of information for a given serial number SKU. 
         [0015]    The installer scenario key comprises (1) a product ID, (2) an identifier that describes the platform on which the product may be run, and (3) an installer code that identifies product information such as whether the product is a subscription product, whether the product is sold in an individualized manner via retail or packaged for wholesale distribution in conjunction with a high volume product, in what region of the world the product is intended for sale, what languages the product allows for use, and the like. 
         [0016]    When a user purchases a subscription product, a service account object (SAO) is created for the user and stored in a user profile. The SAO contains subscription details for a given subscription. If a user has subscriptions to multiple products, the user profile will contain an SAO for each subscription. The SAO is created using the subscription provisioning/renewal SKU of the subscription product purchased by the user. The provisioning/renewal SKU is looked up in the source provisioning table, and the serial number SKU, numeric product version and installer scenario key are retrieved from the source provisioning table and stored in the SAO in a user profile. 
         [0017]    When a user wants to activate a new subscription, for example, from an ADOBE® CREATIVE SUITE® 5.5 Suite subscription to an ADOBE® CREATIVE SUITE® 6 Master Collection subscription or an ADOBE® CREATIVE CLOUD® subscription, an application manager on the client computer sends a request from the client computer to an entitlement service module. The request includes user information and product information. The entitlement service module uses the user information sent with the request to retrieve a user profile including the user&#39;s SAO details. The entitlement service module retrieves the installer scenario key, serial number, and version of the upgraded subscription from the SAO details. 
         [0018]    A validation service module validates the installer scenario key by comparing the installer scenario key to a list of created installer scenario keys. If the installer scenario key is found to be valid, the installer scenario key is used as an index into a scenario table to retrieve product data. As described previously, product data includes information about how the serialized product should behave, such as whether the product is a subscription, on what platform the product runs, whether the product is sold in an individualized manner via retail or packaged for wholesale distribution in conjunction with a high volume product, what region of the world the product is intended for sale, what languages the product allows for use, and the like. Dominance information is also retrieved from the scenario table. When a user profile includes more than one subscription for a product, dominance information defines which product subscription is dominant, meaning which subscription encompasses more subscription products. For example, ADOBE® CREATIVE SUITE® Master Collection includes ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, ADOBE® ACROBAT®, ADOBE® DREAMWEAVER®, and many more subscription products. Suppose, for example, ADOBE® CREATIVE SUITE® Design Standard includes ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, and ADOBE® ACROBAT®. The subscription product that encompasses more products, in the present example, ADOBE® CREATIVE SUITE® Master Collection, dominates a product containing fewer products, namely ADOBE® CREATIVE SUITE® Design Standard. The retrieved dominance information from the scenario table determines what products are licensed for the user. In the present example, defining ADOBE® CREATIVE SUITE® Master Collection as the dominant subscription entitles the user to activate a license for all subscription products under the ADOBE® CREATIVE SUITE® Master Collection. However, if ADOBE® CREATIVE SUITE® Design Standard were defined as the dominant subscription, the user would be entitled to activate a license for the products ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, and ADOBE® ACROBAT®. 
         [0019]    The serial number for the dominant subscription product and the product data retrieved from the scenario table are sent to the client computer. An application manager on the client computer uses a product id from the returned product data to determine the correct licensing configuration file from which it will load a local license. The application manager then deletes any local license present on the client computer that is associated with the serial number. The deletion is performed in order to reload a new license containing new features if any. For example, a local license for an ADOBE® CREATIVE SUITE® 5.5 Suite will not contain the features of ADOBE® CREATIVE SUITE® 6. The application manager loads and activates the new license, thereby allowing the client computer user access to the product (and any new features in the case of an upgrade). The serial number does not need to be entered by the client computer user thereby relieving the user of keeping track of or risking misplacement of the serial number. 
         [0020]    Various embodiments of an apparatus and method for provisioning subscription products are described. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the claimed subject matter. However, it will be understood by those skilled in the art that the claimed subject matter may be practiced without these specific details. In other instances, methods, apparatuses or systems that would be known by one of ordinary skill have not been described in detail so as not to obscure claimed subject matter. 
         [0021]    Some portions of the detailed description that follow are presented in terms of algorithms or symbolic representations of operations on binary digital signals stored within a memory of a specific apparatus or special purpose computing device or platform. In the context of this particular specification, the term specific apparatus or the like includes a general purpose computer once it is programmed to perform particular functions pursuant to instructions from program software. Algorithmic descriptions or symbolic representations are examples of techniques used by those of ordinary skill in the signal processing or related arts to convey the substance of their work to others skilled in the art. An algorithm is here, and is generally, considered to be a self-consistent sequence of operations or similar signal processing leading to a desired result. In this context, operations or processing involve physical manipulation of physical quantities. Typically, although not necessarily, such quantities may take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared or otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to such signals as bits, data, values, elements, symbols, characters, terms, numbers, numerals or the like. It should be understood, however, that all of these or similar terms are to be associated with appropriate physical quantities and are merely convenient labels. Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout this specification discussions utilizing terms such as “processing,” “computing,” “calculating,” “determining” or the like refer to actions or processes of a specific apparatus, such as a special purpose computer or a similar special purpose electronic computing device. In the context of this specification, therefore, a special purpose computer or a similar special purpose electronic computing device is capable of manipulating or transforming signals, typically represented as physical electronic or magnetic quantities within memories, registers, or other information storage devices, transmission devices, or display devices of the special purpose computer or similar special purpose electronic computing device. 
         [0022]      FIG. 1  depicts a block diagram of a system  100  for provisioning subscription products, according to one or more embodiments of the invention. The system  100  comprises a client computer  102 , and a subscription server  106   
         [0023]    connected to each other through a network  104 . In some embodiments, the client computer  102  is a type of user computing device (e.g., a laptop, a desktop and/or the like) running various applications, such as ADOBE® CREATIVE SUITE® 5.5 Suite or ADOBE® CREATIVE SUITE® 6.0 subscription. The client computer  102  comprises a CPU  104 , support circuits  106  and a memory  108 . The CPU  108  may comprise one or more commercially available microprocessors or microcontrollers that facilitate data processing and storage. The various support circuits  110  facilitate the operation of the CPU  108  and include one or more clock circuits, power supplies, cache, input/output circuits, displays, and the like. The memory  112  comprises at least one of Read Only Memory (ROM), Random Access Memory (RAM), disk drive storage, optical storage, removable storage and/or the like. The memory  112  comprises an operating system  114 , an application manager  116 , a subscription product  118 , user information  120 , product information  122 , and license configuration files  124 . 
         [0024]    According to some embodiments of the invention, the operating system (OS)  114  generally manages various computer resources (e.g., network resources, file processors, and/or the like). The operating system  114  is configured to execute operations on one or more hardware and/or software modules, such as Network Interface Cards (NICs), hard disks, virtualization layers, firewalls and/or the like. Examples of the operating system  114  may include, but are not limited to, Linux, Mac OSX, BSD, Unix, Microsoft Windows, and the like. 
         [0025]    The application manager  116  manages the downloading and provisioning of software products. The application manager  116  may be any download manager, such as an ADOBE® Application Manager, or any manager capable of managing software downloads and activating subscription licenses. The subscription product  118  may be any software subscription product such as an ADOBE® CREATIVE SUITE® 5.5 Suite, ADOBE® CREATIVE SUITE® 6, ADOBE® CREATIVE CLOUD® membership, or any software product provided to a user via a subscription. The subscription product  118  may be a new application or update of an existing application made available by a subscription provider. 
         [0026]    The license configuration files  124  comprise licensing information for the various subscription products  118  installed on the client computer  102 . The user information  120  may include login information that provides access to a subscription server  106  and a user identification number that is associated with the subscriptions of the subscription user. The product information  122  links a subscription product  118  to an appropriate license configuration file  124 . 
         [0027]    The subscription server  106  is a type of computing device (e.g., a laptop, a desktop, a Personal Digital Assistant (PDA) and/or the like). The subscription server  106  comprises a CPU  126 , support circuits  128  and a memory  130 . The CPU  126  may comprise one or more commercially available microprocessors or microcontrollers that facilitate data processing and storage. The various support circuits  128  facilitate the operation of the CPU  126  and include one or more clock circuits, power supplies, cache, input/output circuits, displays, and the like. The memory  130  comprises at least one of Read Only Memory (ROM), Random Access Memory (RAM), disk drive storage, optical storage, removable storage and/or the like. The memory  130  comprises an operating system  131 , a source provision table  132 , an entitlement service module  134 , a validation service module  136 , a scenario table  138 , a file of user profiles  140 , a file of valid serial numbers  142 , and a file of valid installer scenario keys  144 . The user profiles  140 , valid serial numbers  142  and valid installer scenario keys  144  may be stored on the subscription server  106  or stored remotely (not shown). 
         [0028]    The network  104  comprises a communication system that connects computers by wire, cable, fiber optic and/or wireless link facilitated by various types of well-known network elements, such as hubs, switches, routers, and the like. The network  104  may employ various well-known protocols to communicate information amongst the network resources. For example, the network  104  may be a part of the Internet or Intranet using various communications infrastructure, such as Ethernet, Wi-Fi, Wi-Max, General Packet Radio Service (GPRS), and the like. 
         [0029]    The application manager  116  provisions subscription products on the client computer  102 . When a user of the client computer  102  chooses to purchase or upgrade a subscription product  118 , for example, to upgrade from an ADOBE® CREATIVE SUITE® 5.5 Suite subscription to an ADOBE® CREATIVE SUITE® 6 Production Premium subscription or an ADOBE® CREATIVE CLOUD® subscription, the application manager  116  sends a request from the client computer  102  to the entitlement service module  134  on the subscription server  106 . The entitlement service module  134  uses a user ID provided in the request to retrieve a user profile including the user&#39;s service account object (SAO) details from user profiles  140 . If a user profile does not exist for the user, the user creates an account and an SAO is created using a redemption code provided in the request. The SAO is an array of subscriptions stored in the user profile  140 . An SAO exists for each subscription held by the user. The SAO includes subscription information regarding a user&#39;s entitlements for a subscription product  118 . Each SAO includes a provisioning/renewal SKU for the subscription product  118 , a serial number SKU for the subscription product  118 , a numeric product version of the subscription product  118 , and an installer scenario key for the subscription product, as described above. If the user does not have an SAO, meaning the request is for a new rather than upgraded subscription, an SAO is created for the user using information provided in the source provision table  132  as described above. The entitlement service module  134  retrieves the installer scenario key, serial number, and version from the SAO parameters in each SAO of the user profile  140 . 
         [0030]    A validation service module  136  is responsive to the data retrieved by the entitlement service module  134  to validate the installer scenario key. The installer scenario key must exist in the file of valid installer keys  144 . If the installer scenario key is not found in the SAO, for example in the instance where the subscription was provisioned prior to implementation of installer scenario keys, the serial number will be used for validation by verifying the serial number exists in a file of valid serial numbers  142 , and if the serial number is valid an installer scenario key is generated. If the installer key (or serial number) is found to be valid, the installer scenario key is used as an index into a scenario table  138  to retrieve product data. As described previously, product data includes information about how the product should behave, such as whether the product is a subscription, on what platform the product runs, whether the product is sold in retail or volume, what region of the world the product is intended for sale, what languages the product allows for use, and the like. 
         [0031]    Dominance information is also retrieved from the scenario table  138 . When a user profile includes more than one subscription for a product, dominance information defines which product subscription is dominant, meaning which subscription encompasses more subscription products. For example, ADOBE® CREATIVE SUITE® Master Collection includes ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, ADOBE® ACROBAT®, ADOBE® DREAMWEAVER®, and many more subscription products. Suppose, for example, ADOBE® CREATIVE SUITE® Design Standard includes ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, and ADOBE® ACROBAT®. The subscription product that encompasses more products, in the present example, ADOBE® CREATIVE SUITE® Master Collection, dominates a product containing fewer products, namely ADOBE® CREATIVE SUITE® Design Standard. The retrieved information determines what products are licensed for the client computer. In the present example, defining ADOBE® CREATIVE SUITE® Master Collection as the dominant subscription entitles a user to activate a license for all subscription products under the ADOBE® CREATIVE SUITE® Master Collection. However, if ADOBE® CREATIVE SUITE® Design Standard were defined as the dominant subscription, the user would entitle the user to activate a license for the products ADOBE® PHOTOSHOP®, ADOBE® ILLUSTRATOR®, ADOBE® INDESIGN®, and ADOBE® ACROBAT®. 
         [0032]    The serial number of the dominant subscription and the product data for the dominant product retrieved from scenario table  138  are sent to the client computer  102 . The application manager  116  on the client computer  102  looks up a product id from the product data in the product information  122  to determine the correct licensing configuration file  124  from which the application manager  116  will load a local license. The application manager  116  then deletes any local license present on the client computer  102  for the serial number and reloads and activates a new license. 
         [0033]      FIG. 2  depicts a flow diagram of a method  200  for provisioning subscription products as performed by the application manager  116 , the entitlement service module  134 , and the validation service module  136  of the system  100  of  FIG. 1 , according to one or more embodiments of the invention. 
         [0034]    The method  200  starts at step  202  and proceeds to step  204 . At step  204 , the method  200  receives a request to provision a product. The product may be a new product for installation or the product may be an upgrade to a new version of an existing subscription product. The method  200  proceeds to step  206 , where the method  200  facilitates sending the request from a client computer to a subscription server. The method  200  includes user information and product information in the request. The user information comprises a user identification number (user ID). The product information comprises a licensing identification number for the product. The method  200  proceeds to step  208 . 
         [0035]    At step  208 , the method  200  receives the request on the server. The method  200  proceeds to step  210 , where the method  200  retrieves a user profile. The user profile is retrieved using the user ID. The method  200  also retrieves any service account objects (SAOs) for the user. The user will have a SAO for each subscription product to which the user is entitled. The SAO includes information about the user&#39;s entitlements for each subscription product. An SAO may be, for example:

         [0036]    In this example, DSP_SCENARIO_KEY is the installer scenario key described above and DSP_PRODUCT_VERSION is the product version of the subscription product. The installer scenario key will be validated before a subscription product is provisioned. If the DSP_SCENARIO_KEY is absent in the SAO, which may occur if the SAO was provisioned before the use of a scenario key, the serial number found for example, in the “ident” field, will be used for validation. The method  200  proceeds to step  212 , where the method  200  determines whether an installer scenario key exists in the SAO. If the installer scenario key exists in the SAO, the method  200  proceeds to step  214 , where the method  200  determines whether the installer scenario key is valid. The installer scenario key is valid if the installer scenario key exists in a file of valid installer keys. If the installer scenario key is invalid, the method  200  proceeds to step  234  and ends. However, if the installer scenario key is valid, the method  200  proceeds to step  222 . 
         [0037]    If at step  212 , the method  200  determined that an installer scenario key does not exist in the SAO, the method  200  proceeds to step  216 , where the method  200  retrieves a serial number for the subscription product from the SAO. In the example SAO above, the serial number is found in the “ident” field. The method  200  proceeds to step  218 , where the method  200  determines whether the serial number is valid. The serial number is valid if the serial number exists in a file of valid serial numbers. If the serial number is invalid, the method  200  proceeds to step  234  and ends. However, if the serial number is valid, the method  200  proceeds to step  220 , where an installer scenario key is generated by concatenating a product ID, an identifier that describes the platform on which the product may be run, and an installer code as described above. The method  200  proceeds to step  222 . 
         [0038]    At step  222 , the method  200  retrieves product and dominance data from a scenario table. The installer scenario key is used as an index into the scenario table to retrieve the product and dominance data. The product data includes information about how the product should behave, such as whether the product is a subscription, whether the product is sold in retail or volume, what region of the world the product is intended for sale, what languages the product allows for use, and the like. Dominance information is also retrieved from the scenario table. Dominance refers to the user subscription that encompasses the most subscription products therein. For example, a subscription product that includes a number of products, such as ADOBE® CREATIVE SUITE® Master Collection dominates any single product that could be contained therein, such as ADOBE® PHOTOSHOP® or ADOBE® AFTER EFFECTS®. The retrieved dominance information determines what subscription products are licensed for the client computer. Because in the present example, the ADOBE® CREATIVE SUITE® Master Collection is dominant, the license for the ADOBE® CREATIVE SUITE® Master Collection is provisioned, rather than provisioning a license for simply ADOBE® PHOTOSHOP®. The method  200  proceeds to step  224 . 
         [0039]    At step  224 , the method  200  facilitates sending the serial number of the dominant subscription product and the product data to the client computer. The method  200  proceeds to step  226 , where the method  200  receives the serial number and product data on the client computer. The method  200  proceeds to step  228  where the method  200  determines a correct license that is to be activated for the subscription product. The method  200  looks up a product ID provided in the product data in a product information file. The product ID in the product information file is associated with a license configuration file that will be activated to provision the subscription. The method  200  proceeds to step  230  where the method  200  deletes a local license for the serial number that was received from the subscription server, if one exists. The method  200  proceeds to step  232 , where the license configuration file found in the product information file that was associated with the product ID is loaded and the license activated. The method  200  proceeds to step  234  and ends.
