Abstract: Disclosed herein are system, method, and computer program product embodiments for quorum-based replication of data records. In one embodiment, a read request for reading a record is received from a user node on a replica node of a cluster of replica nodes. The record is then determined not committed on the replica node. In response to the determination, an update message indicative of whether the number of replica nodes on which the record is durable exceeds a threshold is received on the replica node. In response to the number of replica nodes exceeds the threshold, a value of the record on the replica node is transmitted to the user node.

Abstract: An application complementation module may access application data from an application repository, the application data associated with a first application. The data collections of a data service provider (e.g., OData service) used in the first application and at least one navigation used in the first application to navigate between the data collections are determined based on the application data. Service metadata (e.g., Entity Data Model (EDM)) from the data service provider is searched for new navigations between the used data collections that are different from the navigations used in the first application. An application that is complementary (e.g., provides different or complementary navigations) to the first application may then be generated based on the data collections used in the first application and any new navigations between the data collections discovered from the service metadata. A recommendation regarding the generated application may be provided to a user of the first application.

Abstract: Embodiments associate a relevant semantic data type (e.g., date) with incoming raw data (e.g., a column of digits) which lacks metadata. Assignment of semantic data type is inferred from a plurality of features. A first step determines a first feature comprising success rate in converting the raw data into various semantic data types. Then, alignment between observed/reference distributions of other features (e.g., data first digit, data length) is determined per-semantic data type. Total scores for each semantic data type are calculated from the combined features, and used as a basis for ranking the semantic data types. The total scores may reflect a weighting of the various features. In a second step, top-ranked semantic data types may be further differentiated from one another by applying additional features. User feedback regarding accuracy of semantic data type assignment, may be incorporated into training data used to modify the feature reference distributions.

Abstract: Embodiments protect against security vulnerabilities arising from 3rd party JavaScript code. A browser receives from a server, a document including a first JavaScript. The browser in turn references a list stored in a database to recognize the first JavaScript as originating from other than the server. This recognition process may involve obtaining a stacktrace. The browser then references a second JavaScript in order to instrument a document object model (DOM) feature (e.g., global API, DOM element-attached API, DOM node property) to sanitize the first JavaScript. For instrumenting a global API, this may comprise overwriting a global reference in the first JavaScript with a replacement reference to a sanitization function. For instrumenting the DOM element-attached API or the DOM node property, the instrumenting may comprise altering a prototype of the DOM node element. The browser causes the DOM feature to sanitize the first JavaScript, and passes a sanitized JavaScript for execution.

Abstract: Methods, systems, and articles of manufacture are provided for oblivious order preserving encryption. A method may include: traversing, by a cloud service provider, an order preserving encryption (OPE) tree based on a result of an oblivious comparison performed by a data owner and a data client, the OPE tree having nodes that each correspond to a ciphertext of data associated with the data owner, the ciphertext of the data being stored at the cloud service provider, and a relative position of the nodes within the OPE tree corresponding to an order that is present in the data associated with the data owner; and determining, based on the traversing of the OPE tree, an OPE encoding for an input value from the data client, the OPE encoding for the input value indicative of a position of a node corresponding to the input value within the OPE tree.

Abstract: Cloud-based data is securely retrieved by obfuscating access patterns. A cloud storage system receives a request for data from a remote client that specifies a key. Thereafter, the cloud storage system iterates through an index to identify all locations corresponding to the specified key. Such index is generated by applying a series of j hash functions to each key resulting in a j different tables forming part of the index. Using the index, the cloud storage system returns data from the identified locations to the client. As each write operation works by using non-deterministic encryption, the write operation changes the records stored in this data structure, and when the record is not changed, the algorithm simply rewrites the data which is stored in the data structure by rewriting the same value back again. However since, a nondeterministic encryption is utilized, it makes it indistinguishable as to when new data was written and when existing data is rewritten.

Using the attribute value derivation function, a target attribute data value is derived. A user interface is generated to display the derived target attribute data value.

Abstract: Execution of a page flusher is initiated in an in-memory database system in which pages are loaded into memory and having associated physical disk storage by a resource flush thread using a queue. Thereafter, pages are identified that have been loaded into the memory of the database system and which have been modified. These identified pages are to be flushed to the physical disk storage. Each page is assigned with a different ordered physical page number. These identified pages are added to the queue. Subsequently, asynchronous write I/O is triggered causing the identified pages to be flushed to the physical disk storage and stored in the physical disk storage according to their assigned physical page numbers such that, if at least one predetermined performance condition is met, a subset of the identified pages in the queue are flushed to physical disk storage.
