The protocol also recommended annotating metabolites with structure-based identifiers, such as the IUPAC International Chemical Identifier (InChI) and the Simplified Molecular-Input Line-Entry System (SMILES).
The algorithm matches interactor molecules based on standard identifiers such as UniProtKB (14), RefSeq (15), ROGID (16), or ChEBI (17) accession numbers.
It is important to note that for many of these studies, particularly those that use deterministic methods, linkage is based on unique identifiers such as social security number or health record number that are used by individuals throughout a lifetime and across the spectrum of health and social services [ 11, 20, 21].
Quantin et al. [ 24][ 25] have described a system which uses hashed linkage keys, based on an ensemble of partial identifiers such as name, sex and date-of-birth, for epidemiological and health service evaluation follow-up studies.
The VAED is episode of care based, and the DH has linked these episodes using identifiers such as hospital record number (if episodes occurred in the same hospital) and the first 8 digits of Medicare card number, as well as identifiers such as date of birth, gender, postal code, country of birth and the first three digits of first or middle name (if episodes occurred in different hospitals).
Input associations can be derived from any data mining method as long as node labels are either gene names, identifiers such as ENSEMBL and ENTREZ or chromosome based positions.
Users may access a compound of interest with a variety of identifiers such as InChI Keys, database IDs or common names, or with structure based tools like substructure and structural similarity searching.
Data protection laws apply to information about people; from identifiers such as name, address, employment history or medical records, to more subtle identifiers, such as social networking content, browser history or call log.
"Should the need arise, and technology improve, other personal identifiers such as a persons' fingerprints or iris scan may be prescribed in the migration regulations".
"Nothing in this data set applies to or requires the retention of destination web address identifiers, such as destination IP addresses or URLs".
The NSA also conducted about 9,500 queries of associated "metadata" using US persons' identifiers – such as a phone number or email address - in 2013, and considers 36% of such queries "duplicative".
