摘要:
A computer-implemented service recommends digital works (and/or creators of works) to a user based on works currently or previously played or downloaded by the user on a player device or based on playlists stored on the player device. The works may be, for example, music files, video files, electronic books, or other digital content for playing by users. A user may thus obtain personalized recommendations that are based on works obtained from sources (web sites, physical CDs, etc.) that are independent of the recommendations system. In one embodiment, the service identifies pairs of works (and/or work creators) that are similar to each other by virtue of the relatively high frequency with which they co-occur on playlists or within play histories of users. The resulting mappings are used to provide recommendations to users.

Disclosed are various systems, methods, and other embodiments for the secure storage of files and the like. In one example, a determination is made in a server as to whether an entity indicated in a request received in the server is authorized to transfer a file from a client to a mass storage system over a network. A plurality of instructions are obtained in the server to send to the client, where the instructions are configured to control activity of the client in transferring the file from the client to the mass storage system over the network. The instructions are sent to the client in order to implement the transfer of the file from the client to the mass storage system.

The resulting mappings of works to related works are in-turn used to select works to recommend to users.

Various computer-implemented services are disclosed for increasing the utility of electronic wish lists, and for assisting users in making gift purchases. One such service automatically notifies a user when an item being accessed in an electronic catalog is on, or is similar to an item on, an electronic wish list of an “affiliated” user. The affiliations may be created explicitly by the users (e.g., by completing an online form), and/or implicitly based on actions performed by the users (e.g., when one user purchases a gift for another user). Another service automatically reminds a first user who is affiliated with a second user when a known or inferred gift-giving event of the second user is approaching. The reminder may include a link to a wish list of the second user, and/or may include or provide a link for viewing personalized gift recommendations for the second user.
摘要:
One embodiment of the present invention distributes data via a network to remotely located users. Historical purchase information for a first user is stored in a database. Authorization is received over a network from the first user allowing a second user to view at least a portion of the historical purchase information. In addition, the first user selectively specifies which historical purchase information may be viewed by the second customer. An electronic notification is transmitted to the second user, wherein the notification informs the second user of the first user's authorization.
摘要:
A facility for determining whether to consistency-check a cache entry is described. The facility randomly or pseudorandomly selects a value in a range. If the selected value satisfies a predetermined consistency-checking threshold within the range, the facility consistency-checks the entry, and may decide to propagate this knowledge to other cache managers. If, on the other hand, the selected value does not satisfy the consistency-checking threshold, the facility determines not to consistency-check the entry.

摘要:
An electronic book distribution system encrypts distributed electronic books (“eBooks”) with a content key. The content key is in turn encrypted with a voucher key. The voucher key for a particular eBook is generated based on a combination of (a) an ID or serial number of an eBook reader device to which the eBook is being distributed, (b) a user account secret associated with a user of the eBook reader device, and (c) metadata associated with the eBook itself.

Systems, methods, and computer-readable media provide a requesting device with access to a service. In one implementation, a server stores a token decryption key for validating an encrypted token. The server receives the encrypted token and a digital signature generated using a signature creation key from a client device, and decrypts the token with the token decryption key. The server extracts a signature validation key from the token, and validates the digital signature using the signature validation data. The system provides the client device with access to the service, based on whether the digital signature is validated.

Objects in a content delivery network are modified at delivery to users. Individual content servers include copies of the content objects and receive requests from users for a copy of the object. The request includes a program from the content provider on how the content object is to be modified at delivery to the user. The program is executed on delivery of the object to provide the user with a modified content object. Modification can occur as the content is delivered from the content server to the user.
