Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

Abstract: Among other things, one or more techniques and/or systems are provided for updating a model for generating a health profile of an industrial asset based upon data pertaining to the industrial asset. The health profile comprises a maintenance plan(s), which respectively comprise one or more recommended maintenance actions to be performed with respect to the industrial asset during a prediction period. The model may be periodically and/or intermittently updated based upon a comparison between the recommended maintenance actions and actual events of the industrial asset during the prediction period. Moreover, in some embodiments, different models may be selected for generating future health profiles of the industrial asset based upon a comparison between the recommended maintenance actions and actual events of the industrial asset during the prediction period.

Abstract: Among other things, one or more techniques and/or systems are provided for generating a health profile of an industrial asset based upon data pertaining to such an industrial asset. The health profile describes an expected condition of the industrial asset during a prediction period, a predicted cause of the expected condition, and/or a predicted impact of the expected condition. In some embodiments, the health profile is generated using a model that is configured to be periodically and/or intermittently updated. Further, in some embodiments, a diagnostic profile may be generated describing diagnostic actions that may be taken to improve predictions included within a health profile and/or to improve a confidence in one or more of those predictions.

Abstract: Among other things, one or more techniques and/or systems are provided for developing a criticality profile of an industrial asset. The criticality profile describes the importance of the industrial asset to a system in terms of one or more criticality metrics and/or one or more confidence profiles. Such metrics may include an operational metric indicative of the operation impact of the industrial asset on a system if the industrial asset remains unchanged or enters a degraded or improved state, a restoration metric indicative of a complexity of restoring the industrial asset to an operational state from the unchanged or degraded state and/or complexity of improving the industrial asset to an improved state, and/or an interdependency metric indicative of a relationship between the industrial asset and one or more other industrial assets and/or between the industrial asset and one or more structures in an environment associated with the industrial asset.

Abstract: Among other things, one or more techniques and/or systems are provided for developing a health profile of an industrial asset based upon data pertaining to such an industrial asset. At least some of the data is transformed into primary state indicators, respectively representative of the status or condition of an aspect of the industrial asset. Using the primary state indicators, one or more events that are likely to occur to the industrial asset are identified and a health profile is developed based upon such events. The health profile may describe maintenance actions that will reduce a likelihood of an event(s) occurring, may describe a business impact on an entity associated with the industrial asset if an event(s) occurs, and/or may describe a performance impact on the industrial asset if an event(s) occurs, for example.
