摘要:
In one embodiment of the present invention, a source point of a supply chain secures shipment of an object by devising an encryption key and encrypting a message using the encryption key to produce an encrypted message. A portion or portions of the encryption key and the encrypted message are included or incorporated within the object to be shipped, packaging surrounding the object, and/or labels affixed to the object or packaging, prior to shipping the object to a destination point within the supply chain. Upon receipt of the object from the supply chain, the destination point can extract the portion or portions of the encryption key and the encrypted message from the object, packaging surrounding the object, and/or labels affixed to the object or packaging, obtain the remaining portion of the encryption key directly from the source point, reassemble the encryption key, and decrypt the encrypted message to produce a computed message. The destination point can then obtain the original message from the source point and compare the original message to the decrypted message in order to determine whether or not the shipment is authentic.

There is disclosed a method of identifying a product involving generating a code unique to the product, said code being provided by a multitude of individual identifiers, applying the multitude of the identifiers of the code to the packaging of the product as a pattern to identify the product. The method also involves applying a sub-set of two or more of the multitude of the identifiers of said code to the product, said sub-set of the multitude of the identifiers of the code being applied so they will be presented in the same pattern order as they appear in the pattern order of the multitude of the identifiers of the code applied to the packaging. The product can be identified with a reasonable likelihood of being a genuine product by determining that a presented pattern order of the sub-set of the multitude of the identifiers applied to the product corresponds to a presented pattern order within the multitude of the identifiers applied to the packaging.

A system for distinguishing a package includes a plurality of identifiers, where at least one of the identifiers is intentionally non-functional. The system also includes an identifier indicator that indicates the identity of the at least one of the identifiers that is intentionally non-functional. In addition, the identifier indicator is stored on at least one of the package and a database and is accessible by a user to authenticate the package.

A coating for an object having identifying indicia disposed thereon. An ink layer contacts at least a portion of the identifying indicia. The ink layer obscures the portion when exposed to light within a predetermined wavelength range, and the ink layer reveals a predetermined area of the portion when exposed to light outside of the predetermined wavelength range.

A plurality of differential data stores are stored in persistent storage media. In response to receiving a first request to store a particular data object, one of the differential data stores that are stored in the persistent storage media is selected, wherein selecting the one differential data store is according to a criterion relating to compression of data objects in the differential data stores. The selected differential data store is copied into temporary storage media, where the copying is not delayed after receiving the first request to await receipt of more requests. The particular data object is inserted into the copy of the selected differential data store in the temporary storage media, where the inserting is performed without having to retrieve more data from the selected differential store in the persistent storage media. The selected differential data store in the persistent storage media is replaced with the copy of the selected differential data store in the temporary storage media that has been modified.
摘要:
Data processing apparatus comprising: a chunk store containing specimen data chunks, a manifest store containing a plurality of manifests, each of which represents at least a part of a data set and each of which comprises at least one reference to at least one of said specimen data chunks, a sparse chunk index containing information on only some specimen data chunks, the processor being operable to: process input data into input data chunks; identify manifests having at least one reference to one of said specimen data chunks that corresponds to one of said input data chunks and on which there is information contained in the sparse chunk index; and prioritize the identified manifests for subsequent operation.
摘要:
In a method for generating a query plan for estimating a number of unique entry counts of an attribute in a database, a sample of entries in the database is identified, at least one of a sampling percent and a coefficient of variance of the entries in the sample is identified, and a skewness of the entries in the sample is calculated. In addition, at least one of a plurality of estimators is selected based upon the skewness of the entries and at least one of the sampling percent and the coefficient of variance of the entries in the sample. Moreover, a query plan is generated from the selected at least one of the plurality of estimators. A query optimizer for performing the method is provided.
摘要:
A method of identifying a provenance of a document is provided. The method may include obtaining a query document that is included in a document set comprising a plurality of documents. The method may also include grouping the plurality of documents into a plurality of fine clusters based on a textual similarity between the plurality of documents. The method may also include identifying a target fine cluster within the plurality of fine clusters, the target fine cluster including the query document. The method may also include ordering the documents included in the target fine cluster based, at least in part, on metadata associated with each of the documents to identify a source document. The method may also include generating a query response that includes the source document.
