Uva Software’s scanii-lambda

A Sam-Packaged AWS Lambda client to the scanii.com content processing engine. For a detailed walk-through of deploying this application see: https://docs.scanii.com/article/151-how-do-i-analyze-content-stored-on-amazon-s3.

How it works

This is, essentially, a series of lambda functions packaged in a one-click deployable application that configures everything needed so your S3 objects are submitted automatically to scanii’s content analysis API. Once the content is processed, you can choose from a couple of different actions:

1. Tag the content - this is defaulted to on and adds the following tag to objects processed:
   1. ScaniiId -> the resource id of the processed content
   2. ScaniiFindings -> list of identified findings (content engine dependent)
   3. ScaniiContentType -> the identified content type of the file processed
2. Delete the object with findings - this is defaulted to off and will delete S3 objects with findings (such as malware or NSFW content) - for a full list of available content identification see https://support.scanii.com/article/20-content-detection-engines

Building and running tests

Tests utilize Mocha and are triggered into NPM, we provide a makefile to tie everything together:

$ make test
