Methods and apparatus for automated redaction of content in a document
View Patent ↗A redaction process obtains redaction data indicating content to be redacted in a document. In addition, the redaction process obtains non-redaction data indicating content not to be redacted in the document. Furthermore, the redaction process obtains proximity data indicating proximate expressions to be matched against the document. In this manner, the redaction process processes the redaction data, non-redaction data and proximity data against the document to produce a redact list and a potential list. Upon receiving user selections from both the redact and the potential lists, the redaction process applies a redaction function to the document to produce a redacted version of the document.
1. A method comprising:
obtaining, by a processing device, redaction data identifying content to be redacted in a document and non-redaction data identifying content not to be redacted in the document;
determining, by the processing device, that (i) a phrase from the document is included in one of the redaction data and the non-redaction data and (ii) that a word from the phrase is included in another of the redaction data and the non-redaction data; and
producing, by the processing device, a redacted version of the document by applying a conflict resolution rule with respect to the phrase, wherein the conflict resolution rule comprises applying the one of the redaction data and the non-redaction data that includes the phrase and ignoring the other of the redaction data and the non-redaction data with respect to the word in the phrase.
2. The method of claim 1 , wherein producing the redacted version comprises:
presenting the phrase in an interface indicating that the word is included in the other of the redaction data and the non-redaction data based on the conflict resolution rule being applicable with respect to the phrase;
receiving an input via the interface to apply the conflict resolution rule; and
applying the conflict resolution rule.
3. The method of claim 2 , wherein presenting the phrase in the interface comprises:
presenting the phrase in one of a redaction list generated based on applying the data to the document and a non-redaction list generated based on applying the non-redaction data to the document; and
presenting the word in another of the redaction list and the non-redaction list.
4. The method of claim 2 , wherein presenting the phrase in the interface comprises:
presenting the phrase in a potential list comprising content to which the conflict resolution rule is applicable; and
excluding the phrase from a redaction list generated based on applying the redaction data to the document or a non-redaction list generated based on applying the non-redaction data to the document.
5. The method of claim 1 , wherein the conflict resolution rule is automatically applied with respect to the phrase without requesting additional input regarding redaction or non-redaction of the phrase.
6. The method of claim 1 , further comprising:
determining, by the processing device, that (i) an additional phrase from the document is included in one of the redaction data and the non-redaction data and (ii) that an additional word from the additional phrase is included in another of the redaction data and the non-redaction data; and
identifying, by the processing device, an additional conflict resolution rule specifying that the additional word is exempt from the conflict resolution rule;
wherein the redacted version of the document is produced by excluding the additional word from application of the conflict resolution rule based on the identified additional conflict resolution rule.
7. The method of claim 6 , wherein the additional phrase is included in the non-redaction data and the word is included in the redaction data, wherein excluding the additional word from application of the conflict resolution rule comprises redacting the word based on the identified additional conflict resolution rule and the redaction data.
8. A non-transitory computer readable storage medium comprising executable instructions encoded thereon operable on a computerized device to perform processing comprising:
obtaining redaction data identifying content to be redacted in a document and non-redaction data identifying content not to be redacted in the document;
determining that (i) a phrase from the document is included in one of the redaction data and the non-redaction data and (ii) that a word from the phrase is included in another of the redaction data and the non-redaction data; and
producing a redacted version of the document by applying a conflict resolution rule with respect to the phrase, wherein the conflict resolution rule comprises applying the one of the redaction data and the non-redaction data that includes the phrase and ignoring the other of the redaction data and the non-redaction data with respect to the word in the phrase.
9. The non-transitory computer readable storage medium of claim 8 , wherein producing the redacted version comprises:
presenting the phrase in an interface indicating that the word is included in the other of the redaction data and the non-redaction data based on the conflict resolution rule being applicable with respect to the phrase;
receiving an input via the interface to apply the conflict resolution rule; and
applying the conflict resolution rule.
10. The non-transitory computer readable storage medium of claim 9 , wherein presenting the phrase in the interface comprises:
presenting the phrase in one of a redaction list generated based on applying the redaction data to the document and a non-redaction list generated based on applying the non-redaction data to the document; and
presenting the word in another of the redaction list and the non-redaction list.
11. The non-transitory computer readable storage medium of claim 9 , wherein presenting the phrase in the interface comprises:
presenting the phrase in a potential list comprising content to which the conflict resolution rule is applicable; and
excluding the phrase from a redaction list generated based on applying the redaction data to the document or a non-redaction list generated based on applying the non-redaction data to the document.
12. The non-transitory computer readable storage medium of claim 8 , wherein the conflict resolution rule is automatically applied with respect to the phrase without requesting additional input regarding redaction or non-redaction of the phrase.
13. The non-transitory computer readable storage medium of claim 8 , wherein the operations further comprise:
determining that (i) an additional phrase from the document is included in one of the redaction data and the non-redaction data and (ii) that an additional word from the additional phrase is included in another of the redaction data and the non-redaction data; and
identifying an additional conflict resolution rule specifying that the additional word is exempt from the conflict resolution rule;
wherein the redacted version of the document is produced by excluding the additional word from application of the conflict resolution rule based on the identified additional conflict resolution rule.
14. The non-transitory computer readable storage medium of claim 13 , wherein the additional phrase is included in the non-redaction data and the word is included in the redaction data, wherein excluding the additional word from application of the conflict resolution rule comprises redacting the word based on the identified additional conflict resolution rule and the redaction data.
15. A computer system comprising:
a processor;
a non-transitory computer readable storage medium storing instructions associated with an application executable by the processor; and
an interconnect coupling the processor and the non-transitory computer readable storage medium,
