A method of operating/renting keyless motor vehicles includes configuring a user's smartphone to wirelessly communicate with the security systems of at least a selected keyless vehicle, whereby the user's smartphone can transmit a digital key to the security system of a keyless vehicle to permit operation thereof. A digital key for a selected keyless vehicle is transmitted to the user's smartphone, and the user is provided with an authorization code that can be used to gain entry into the selected vehicle. The user enters the authorization code using the user input device of the selected keyless vehicle, and the user's smartphone then transmits the digital key to the security system of the selected keyless vehicle. The user can enter and operate the selected vehicle without receiving a conventional key and/or key fob.

Embodiments are directed to securing data in the cloud, securely encrypting data that is to be stored in the cloud and to securely decrypting data accessed from the cloud. In one scenario, an instantiated trust service receives information indicating that a trust server is to be instantiated. The trust service instantiates the trust server, which is configured to store key references and encrypted keys. The trust service receives the public key portion of a digital certificate for each publisher and subscriber that is to have access to various specified portions of encrypted data. A data access policy is then defined that specifies which encrypted data portions can be accessed by which subscribers.

A digital escrow pattern for data services can include selective access for obscured data at a remote site or in a cloud service, distributing trust across multiple entities to avoid a single point of data compromise. Based on the pattern, a "trustworthy envelope" for any kind of payload enables curtained access through a variety of decorations or seals placed on the envelope that allow for a gamut of trust ranging with guarantees such as, but not limited to, confidentiality, privacy, anonymity, tamper detection, integrity, etc. For instance, XML tags can be applied or augmented to create trust envelopes for structured XML data. Some examples of mathematical transformations or 'decorations' that can be applied to the XML data include, but are not limited to, size-preserving encryption, searchable-encryption, or Proof(s) of Application, blind fingerprints, Proof(s) of Retrievability, etc.

The present disclosure provides techniques for adjusting a temporal gain parameter and for adjusting linear prediction coefficients. A value of the temporal gain parameter may be based on a comparison of a synthesized high-band portion of an audio signal to a high-band portion of the audio signal. If a signal characteristic of an upper frequency range of the high-band portion satisfies a first threshold, the temporal gain parameter may be adjusted. A linear prediction (LP) gain may be determined based on an LP gain operation that uses a first value for an LP order. The LP gain may be associated with an energy level of an LP synthesis filter. The LP order may be reduced if the LP gain satisfies a second threshold.

The present invention extends to methods, systems, and computer program products for forming data responsive to a query. Responding to a query can include selecting data views on top of data sources. A data catalog stores data elements from different data sources and stores links between data elements from the different data sources. A view can be selected for a query based on one or more of: classification of data included in the data catalog or prior usage of data included in the data catalog. A selected data view is populated with data elements from the data catalog using the links to determine that data elements spanning multiple data sources satisfy the query. The data catalog can be used to identify relationships between data elements from different data sources that would not otherwise be identified.

The present disclosure provides techniques for adjusting a temporal gain parameter and for adjusting linear prediction coefficients. A value of the temporal gain parameter may be based on a comparison of a synthesized high-band portion of an audio signal to a high-band portion of the audio signal. If a signal characteristic of an upper frequency range of the high-band portion satisfies a first threshold, the temporal gain parameter may be adjusted. A linear prediction (LP) gain may be determined based on an LP gain operation that uses a first value for an LP order. The LP gain may be associated with an energy level of an LP synthesis filter. The LP order may be reduced if the LP gain satisfies a second threshold.

In speech processing systems, compensation is made for sudden changes in the background noise in the average signal-to-noise ratio (SNR) calculation. SNR outlier filtering may be used, alone or in conjunction with weighting the average SNR. Adaptive weights may be applied on the SNRs per band before computing the average SNR. The weighting function can be a function of noise level, noise type, and/or instantaneous SNR value. Another weighting mechanism applies a null filtering or outlier filtering which sets the weight in a particular band to be zero.

In one scenario, an instantiated trust service receives information indicating that a trust server is to be instantiated. The trust service instantiates the trust server, which is configured to store key references and encrypted keys. The trust service receives the public key portion of a digital certificate for each publisher and subscriber that is to have access to various specified portions of encrypted data. A data access policy is then defined that specifies which encrypted data portions can be accessed by which subscribers.

Embodiments are directed to mapping encryption policies to user data stored in a database using a policy column uniform resource identifier (URI). In one scenario, a computer system receives the following: a database schema name that identifies the name of a specified schema within a relational database in which user data is stored, a table name that identifies a specified table within the relational database, a column name that identifies a specified column in the specified table and a namespace identifier that identifies a set of relational databases. The computer system also receives an indication that identifies which type of encryption is to be applied when encrypting the column of data specified by the column name. The computer system then generates a policy column URI that includes a hierarchical string comprising the namespace identifier, the database schema name, the table name and the column name. 1. A computer system comprising the following:one or more processors;system memory; ["an act of receiving the following: a database schema name that identifies the name of a specified schema within a relational database in which at least a portion of a user's data is stored, a table name that identifies a specified table within the relational database, a column name that identifies a specified column in the specified table and a namespace identifier that identifies a set of relational databases where each column identified by the column name has the same semantics for each database in the set;", 'an act of receiving an indication that identifies which type of encryption is to be applied when encrypting the column of data specified by the column name; and', 'an act of generating a policy column URI, wherein the policy column URI comprises a hierarchical string comprising the namespace identifier, the database schema name, the table name and the column name., 'one or more computer-readable storage media having stored thereon computer-executable instructions that, ...
