Patent number: 9686261Abstract: Systems and methods are described for delegating permissions to enable account access. The systems utilize a delegation profile that can be created within a secured account of at least one user. The delegation profile includes a name, a validation policy that specifies principals which may be external to the account and which are permitted to assume the delegation profile, and an authorization policy that indicates the permitted actions within the account for those principals which are acting within the delegation profile. Once the delegation profile is created, it can be provided to external principals or services. These external principals or services can use the delegation profile to obtain credentials for performing various actions in the account using the credentials of the delegation profile.Type: GrantFiled: February 23, 2015Date of Patent: June 20, 2017Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Gregory B. Roth, Nathan R. Fitch, Kevin Ross O'Neill, Graeme D. Baer, Bradley Jeffery Behm, Brian Irl Pratt

Patent number: 9660972Abstract: A credential, such as a password, for an entity is used to generate multiple keys. The generated keys are distributed to credential verification systems to enable the credential verification systems to perform authentication operations. The keys are generated such that access to a generated key allows for authentication with a proper subset of the credential verification systems. Thus, unauthorized access to information used by one authentication system does not, by itself, allow for successful authentication with other authentication systems.Type: GrantFiled: June 25, 2012Date of Patent: May 23, 2017Assignee: Amazon Technologies, Inc.Inventors: Gregory B. Roth, Graeme D. Baer

Publication number: 20170134367Abstract: Session-specific information stored to a cookie or other secure token can be selected and/or caused to vary over time, such that older copies will become less useful over time. Such an approach reduces the ability of entities obtaining a copy of the cookie from performing unauthorized tasks on a session. A cookie received with a request can contain a timestamp and an operation count for a session that may need to fall within an acceptable range of the current values in order for the request to be processed. A cookie returned with a response can be set to the correct value or incremented from the previous value based on various factors. The allowable bands can decrease with age of the session, and various parameter values such as a badness factor for a session can be updated continually based on the events for the session.Type: ApplicationFiled: January 18, 2017Publication date: May 11, 2017Inventors: Gregory B. Roth, Nicholas Alexander Allen, Cristian M. llac

Patent number: 9639825Abstract: In certain embodiments, a system receives a request sent by a device to authorize an operation. The system initiates display of an image encoding a challenge code to allow the device to capture the image and extract the challenge code. The device calculates a response using the challenge code and a seed, and sends the response to the system. In certain examples, the device may send the request over a first channel and the response over a second channel distinct from the first channel. In other examples, the device displays the response and a user inputs the response into a computing system to send to the system.Type: GrantFiled: June 14, 2011Date of Patent: May 2, 2017Assignee: Amazon Technologies, Inc.Inventors: Gregory B.

Patent number: 9628875Abstract: In certain embodiments, a web services system receives a request to provision a device, such as a telephone, as an authentication device. The web services system initiates display of an image communicating a key to allow the telephone to capture the image and to send key information associated with the key. The web services system receives the key and determines that the key information is valid. In response to the determination, the web services system sends a seed to the telephone to provision the telephone to be an authentication device. The telephone can use the seed to generate one-time passcodes to access a service of the web services system.Type: GrantFiled: June 14, 2011Date of Patent: April 18, 2017Assignee: Amazon Technologies, Inc.Inventors: Gregory B. Roth, Nathan R. Fitch, Graeme D. Baer

Patent number: 9607162Abstract: A support system negotiates secure connections on behalf of multiple guest systems using a set of credentials associated with the guest systems. The operation of the secure connection may be transparent to the guest system such that guest system may send and receive messages that are encrypted or decrypted by the support system, such as a hypervisor. As the support system is in between the guest system and a destination, the support system may act as a local endpoint to the secure connection. Messages may be altered by the support system to indicate to a guest system which communications were secured. The credentials may be managed by the support system such that the guest system does not require access to the credentials.Type: GrantFiled: May 18, 2015Date of Patent: March 28, 2017Assignee: Amazon Technologies, Inc.Inventors: Gregory B. Roth, Eric D. Crahen, Graeme D. Baer, Eric J. Brandwine, Nathan R. Fitch

Patent number: 9571481Abstract: A secret distribution system may disclose a secret once to a client computing resource while maintaining the privacy of the message and allowing for recovery from dropped network messages. A claim code may be given to a client which may be sent to the secret distribution system, causing the secret distribution system to send a pending secret to the client. Until a client successfully confirms receipt of the pending secret or the claim code expires, the client may request new pending secrets to replace the prior unconfirmed secrets from the secret distribution system. Once a last-sent pending secret is confirmed by the client to the secret distribution system, the last-sent pending secret may be activated for use and the claim code invalidated.Type: GrantFiled: November 30, 2011Date of Patent: February 14, 2017Assignee: Amazon Technologies, Inc.Inventors: Graeme D.

Patent number: 9450758Abstract: A first request from a client using a first protocol is translated into one or more second requests by a servicer using a second protocol through a virtual request using the first protocol. A client may use parameters of the first protocol to pass virtual request components to the servicer. A format agreement between the client, servicer and/or authentication service may allow the servicer and/or authentication service to translate the virtual request components over the first protocol to one or more second requests using the second protocol. Virtual request components may prove the authenticity of the virtual request received by the servicer to an authentication service. Once satisfied the virtual request is valid, the authentication service may issue a credential to the servicer to send the one or more second requests to an independent service. Virtual requests may be included in various protocols, including credential-based protocols and certificate exchange-based protocols.Type: GrantFiled: March 12, 2012Date of Patent: September 20, 2016Assignee: Amazon Technologies, Inc.Inventors: Nicholas Alexander Allen, Gregory B.

Publication number: 20160205110Abstract: The usage of data in a multi-tenant environment can be controlled by utilizing functionality at the hypervisor level of various resources in the environment. Data can be associated with various tags, security levels, and/or compartments. The ability of resources or entities to access the data can depend at least in part upon whether the resources or entities are also associated with the tags, security levels, and/or compartments. Limitations on the usage of the data can be controlled by one or more policies associated with the tags, security levels, and/or compartments. A control service can monitor traffic to enforce the appropriate rules or policies, and in some cases can prevent encrypted traffic from passing beyond a specified egress point unless the encryption was performed by a trusted resource with the appropriate permissions.Type: ApplicationFiled: March 21, 2016Publication date: July 14, 2016Inventors: Gregory B.

Publication number: 20160191993Abstract: Systems and methods for authentication generate keys from secret credentials shared between authenticating parties and authenticators. Generation of the keys may involve utilizing specialized information in the form of parameters that are used to specialize keys. Keys and/or information derived from keys held by multiple authorities may be used to generate other keys such that signatures requiring such keys and/or information can be verified without access to the keys. Keys may also be derived to form a hierarchy of keys that are distributed such that a key holder's ability to decrypt data depends on the key's position in the hierarchy relative to the position of a key used to encrypt the data. Key hierarchies may also be used to distribute key sets to content processing devices to enable the devices to decrypt content such that sources or potential sources of unauthorized content are identifiable from the decrypted content.Type: ApplicationFiled: March 7, 2016Publication date: June 30, 2016Inventors: Gregory B.

Patent number: 9292621Abstract: Text input that is automatically “corrected” by an auto-correction process can be analyzed to determine whether to also include text as input before the correction. A set of words particular to an environment can be run through a number of auto-correct processes to determine which words are likely to be corrected, as well as the corrected versions. These “corrected” versions can be added to an index or other collection as synonyms, or alternatives, for the uncorrected words. When a request or other input is received that includes a corrected term, a determination can be made as to whether to include content for the synonymous uncorrected term. Such an approach can enable a user to obtain content that is more likely of interest to the user based at least in part upon known corrections made to terms that did not necessarily need correcting.Type: GrantFiled: September 12, 2012Date of Patent: March 22, 2016Assignee: Amazon Technologies, Inc.Inventor: Gregory B.

Patent number: 9256762Abstract: A database access system may protect a field by storing the field as one or more underlying fields within a database. The database engine may not have access to keys used to protect the underlying fields within the database, such as by encryption, while the database access system may have access to the keys. Underlying fields may be used to store protected data and aid in the querying of protected data. The database access system may modify queries to use the underlying fields, which may include encrypting query terms and/or modifying query terms to fit the use of the underlying fields. The database access system may modify query results to match the format of the original query, which may include decrypting protected results and/or removing underlying fields.Type: GrantFiled: December 20, 2011Date of Patent: February 9, 2016Assignee: Amazon Technologies, Inc.Inventors: Gregory B.
