A computing system assigns an anonymous cloud account to a user in response to a determination that identity information of the user is validated for a request to access a cloud. The anonymous cloud account does not reveal an identity of the user to the cloud. The computing system creates mapping data that associates the user with the anonymous cloud account. The cloud does not have access to the mapping data. The computing system facilitates user access to the cloud based on the anonymous cloud account. The cloud generates cloud access pattern data for the anonymous cloud account without determining the identity of the user.

Protecting user identity at a cloud using a distributed user identity system

A server computer system within a network of an organization receives a request from a user to access a cloud account. The request includes a user identifier. The server computer system authenticates the user for access to the cloud account based on the user identifier, identifies one or more predetermined roles associated with the cloud account for the user, and identifies one or more pseudo accounts associated with the cloud account. The server computer system further maps the user to the one or more pseudo accounts, and provides user access to the cloud account based on the mapping and with access privileges corresponding to the one or more pseudo accounts.

Role-based access control using dynamically shared cloud accounts

A computer-implemented method for searching shared encrypted files on third-party storage systems may include (1) receiving, at a server-side computing system, a request from a user to search at least one encrypted file to which a group of users that includes the user shares access, (2) identifying, in response to the request, at least one encrypted search index compiled for and shared by the group of users that enables the encrypted file to be searched, (3) decrypting the encrypted search index with a key with which each user within the group of users has access, and (4) using the decrypted search index to respond to the request from the user. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for searching shared encrypted files on third-party storage systems

A first computer system identifies deduplication metadata for files. The deduplication metadata includes block level information for the files. The first computer system determines relationships that are associated with the files based on the block level information and sends relationship data that describes the relationships that are associated with the files to a second computer system via a network.

Discovering relationships using deduplication metadata to provide a value-added service

Techniques are disclosed for using a false positive-prone data structure to store normalization data for use in an encrypted search context. A file host server in a cloud provider network may provide search functionality for a user's encrypted data by use of a search index. In updating the search index, the server consolidates common identities of the user on different web services (e.g., an e-mail service or a social media service) into a normalized identifier. These normalization values are stored in the false positive-prone data structure (e.g., a colliding hash table, a Bloomier filter, etc.). Consequently, the data structure may return false positives after a search operation. The server may filter out these false positives before returning search results.

Encrypted search acceleration

A computer-implemented method for securing data at third-party storage services may include (1) receiving, at a server-side computing system, a request to provide a user with access to a file that is encrypted, (2) determining, in response to the request, whether a transitory symmetric key of the user is available to encrypt a decryption key with which the file may be decrypted, (3) encrypting the decryption key with the transitory symmetric key of the user if the transitory symmetric key of the user is available or encrypting the decryption key with the public key of an asymmetric key pair designated for the user if the transitory symmetric key of the user is unavailable, and (4) storing the encrypted decryption key. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for securing data at third-party storage services

Techniques for providing access to data in dynamic shared accounts are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system for providing data in dynamic shared accounts. The system may comprise one or more processors communicatively coupled to a network. The one or more processors may be configured to identify a first user associated with an account, identify a second user to have access to the account associated with the first user in the event the first user is unavailable to access data or perform functions associated with the account, map the second user to the account, and provide the second user access to the account based on the mapping and with access privileges associated with the first user.

Techniques for providing access to data in dynamic shared accounts

A computer-implemented method for detecting cloud-based data leaks may include (1) identifying a relational database stored on a third-party storage service, the relational database including a plurality of tuples related by an attribute designated for storing contact information, (2) adding at least one deceptive tuple representing an illegitimate contact and including known false contact information stored under the attribute to the relational database, (3) maintaining a data repository identifying the deceptive tuple as containing false contact information, (4) identifying a contact attempt performed by an attempted use of the known false contact information, and then, in response to identifying the contact attempt, and (5) determining, based on the data repository identifying the deceptive tuple as containing false contact information, that an originator of the contact attempt is implicated in a data leak. Various other methods, systems, and computer-readable media are also disclosed.

Techniques for providing role-based access control using dynamic shared accounts are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system and method for providing role-based access using dynamic shared accounts. For example, the system may comprise one or more processors communicatively coupled to a network. The one or more processors may be configured to: receive a request for access to an account, wherein the request comprises an identifier associated with a user; authenticate the user for access to the account; identify one or more predetermined roles associated with the account for the user; identify one or more pseudo accounts corresponding to the one or more predetermined roles; map the user to the one or more pseudo accounts; and provide user access to the account based on the mapping and with access privileges associated with the one or more predetermined roles associated with the user.

Techniques for providing role-based access control using dynamic shared accounts

A computing system identifies shared cloud accounts of a cloud that are created for an entity. The computing system resides outside of the cloud. The number of shared cloud accounts is less than a number of entity users that use the cloud. The computing system determines that one of the users is authorized to use any of the shared cloud accounts in response to a determination that identity information of the user is valid. The computing system receives a request from the user to access the cloud and determines whether one of the shared cloud accounts is available to be assigned to the user. The computing system adds the request to a queue based on a determination that none of the shared cloud accounts is available and assigns one of the cloud accounts to the user based on a determination that one of the shared cloud accounts is available.

Providing dynamically shared cloud accounts

Techniques for identifying potential malware domain names are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system for identifying potential malware domain names. The system may comprise one or more processors communicatively coupled to a network. The one or more processors may be configured to receive a request for network data, where the request for network data may comprise a domain name. The one or more processors may also be configured to apply a lexical and linguistic analysis to the domain name. The one or more processors may also be configured to identify whether the domain name is a potential malware domain name based on the lexical and linguistic analysis.
