Abstract: Provided is a group-based communication interface, on a computing device, configured to display a defined preview of a resource. The computing device receives a group-based message including a resource request that identifies a requested resource and a resource address. The computing device compares the resource address with a list of subscribed resource addresses and determines from the comparison of the resource address and the subscribed resource addresses that the resource address is associated with a resource provider and is thus a subscribed resource address. In response to determining that the resource address is the subscribed resource address, the computing device provides a defined preview request comprising authentication information to the resource provider, receives defined preview data from the resource provider, and renders the defined preview of the resource based on the defined preview data to the group-based communication interface associated with the group-based message.

Abstract: System and method to produce an anonymized cohort having less than a predetermined risk of re-identification. The method includes receiving a data query of requested traits for the anonymized cohort, querying a data source to find records that possess at least some of the traits, forming a dataset from at least some of the records, and grouping the dataset in time into a first boundary group, a second boundary group, and one or more non-boundary groups temporally between the first boundary group and second boundary group. For each non-boundary group, calculating maximum time limits the non-boundary group can be time-shifted without overlapping an adjacent group, calculating a group jitter amount, capping the group jitter amount by the maximum time limits and by respective predetermined jitter limits, and jittering said non-boundary group by the capped group jitter amount to produce an anonymized dataset. Return the anonymized dataset.

Abstract: In longitudinal datasets, it is usually unrealistic that an adversary would know the value of every quasi-identifier. De-identifying a dataset under this assumption results in high levels of generalization and suppression as every patient is unique. Adversary power gives an upper bound on the number of values an adversary knows about a patient. Considering all subsets of quasi-identifiers with the size of the adversary power is computationally infeasible. A method is provided to assess re-identification risk by determining a representative risk which can be used as a proxy for the overall risk measurement and enable suppression of identifiable quasi-identifiers.

Abstract: A system, method and computer readable memory for determining journalist risk of a dataset using population equivalence class distribution estimation. The dataset may be a cross-sectional data set or a longitudinal dataset. The determine risk of identification can be determined and used in de-identification process of the dataset.
