A determination is made, at a device, as to whether data identifying signals detected at the device include data from a non-stationary wireless beacon. If the data includes data from a non-stationary wireless beacon then observation data including both the data and an associated trusted position of the device is maintained in an observation buffer; otherwise, the observation data is dropped by the device. The observation data from the observation buffer is provided to a service, which determines whether the observation data conforms to one or more patterns, the one or more patterns having been identified based on one or more criteria used by the device in providing the observation data to the service. If the observation data conforms to the one or more patterns then the observation data is maintained by the service; otherwise, the observation data is dropped by the service.

Wireless beacon filtering and untrusted data detection

The subject invention can track and apply user edits to a source document as a sequence of changes. The changes can be applied in a document or spatial order irrespective of temporal factors. The invention can maintain intervals that represent user operations (e.g., insertions, deletions, zero-net-length changes). As well, the invention can infer a location in the original document that corresponds to a particular operation. In accordance therewith, the invention can arrange temporally sequenced user document modifications into an order consistent with the layout of the document file encoding. This functionality of mapping re-sequenced changes into the original document data representation is one novel feature of the invention. The invention can enable portions of the source document loaded into memory on an as-needed basis whereby changes relevant to the instant portion can be made.

Memory optimizing for re-ordering user edits

A system and method for preserving unrepresented data in a document exchanged between applications. Applications handling the document, or computing devices executing the applications may have different capabilities with respect to a particular feature of the document such as certain formatting properties, footnotes, graphical attributes, and the like. Data associated with such features, unrepresented data, is preserved by employing a tree structure for the document and flagging nodes associated with unrepresented data. Flagged nodes are ignored, but preserved, when the document is handled by an application or computing device with different capabilities. When the document is handled again by an application or computing device that is capable of processing those features, the unrepresented data is made available along with any modifications made to the document during the previous handling.
