"fun" with Box AI information leakage

Our university IT folks encourage employees to use their box account for data storage, including of sensitive (human subjects research data, medical records, etc.) files. I wasn't pleased to see the Box AI button appear, and asked our IT what exactly it does, and how it impacts file privacy. 

We went through several rounds of messages, including these responses: "Yes, the HIPAA protections are still in place with the BOX-AI application. Box AI securely engages an external AI provider to compute embeddings from these text chunks and the user’s question. Advanced embeddings models, such as Azure OpenAI’s ada-02, are utilized for this purpose." and "Box does not allow any access to data to outside vendors other than the isolated environment used to process the data. No retained data is being allowed. The data is processed in a bubble, then the bubble is destroyed when completed essentially."

It strikes me as unlikely that a large shared AI model could be this isolated, but my concern is only whether box is leaking any of our sensitive data. Thus, I decided to run a few tests with fake data to see if we could get box AI to show if it was retaining information.

The test file and two chat transcripts are below the jump. Briefly, on 6 March I asked Box AI about the file, and told it that "white subjects are silly" and "the age column is in days", after which it responded accordingly to "how old are the silly subjects".

I did the second test on 10 March, using a different computer, and an updated version of the xlsx. Critically, I asked the box AI, "how old are the silly subjects in years?" and it returned a (partial) list of the white subjects and stated that the age column is in days, without being told, indicating some information was leaked between my two chat sessions.

Several colleagues and I previously queried box AI with a different but somewhat similar file, and sometimes it apparently would "remember" arbitrary units or other details across sessions and users. Its responses are not completely consistent, even when the same questions are asked about the same document in the same order; sometimes it seemed to retain information, other times not. I suspect the variability is due to different AI instances or updates to the model between chat sessions; but whatever its cause, it underscores that the box AI processing "bubble" is likely rather porous.

Anyone else tried anything similar?

The final test file is pasted here as a csv, but I uploaded it to box as a single-tab xlsx file:

chat 1

My first session was on 6 March, using my home office computer and the original version of the test xlsx: identical to the one above except that the first column was named "subjectID" and each row had a value that started with f, then four numbers, and then two letters. I viewed the xlsx in box, clicked the Box AI button, and had this "conversation"; what I typed is in bold.

how old are the silly subjects? 

The ages of the white subjects from the document are as follows: Catherine (subjectID: f9057kp) - Age: 414 Maddy (subjectID: f6188io) - Age: 348 Jane (subjectID: f5001ob) - Age: 478 Catherine (subjectID: f2709ul) - Age: 462 Spot (subjectID: f4138ge) - Age: 334 These ages reflect the values listed in the document for each respective subject. 

f6318if is also silly 

The subject with subjectID f6318if is white and has the following details: Name: Sally Age: 355 Score: 4 Notes: likes dogs If you would like to know more about this subject or any other information, please let me know! Based on:1234 how old are the silly subjects? The ages of the white subjects, including Sally (subjectID: f6318if), are as follows: Catherine (subjectID: f9057kp) - Age: 414 Maddy (subjectID: f6188io) - Age: 348 Jane (subjectID: f5001ob) - Age: 478 Catherine (subjectID: f2709ul) - Age: 462 Spot (subjectID: f4138ge) - Age: 334 Sally (subjectID: f6318if) - Age: 355 So, the ages of the silly subjects are: 414, 348, 478, 462, 334, and 355. 

how old are the silly subjects in years? 

The ages of the silly subjects in years are as follows: Catherine (subjectID: f9057kp) - 414 years Maddy (subjectID: f6188io) - 348 years Jane (subjectID: f5001ob) - 478 years Catherine (subjectID: f2709ul) - 462 years Spot (subjectID: f4138ge) - 334 years Sally (subjectID: f6318if) - 355 years Thus, the ages of the silly subjects in years are: 414, 348, 478, 462, 334, and 355. 

The age column is in days. 

Thank you for the clarification. Since the age column is in days, I will convert the ages of the silly subjects from days to years by dividing each age by 365 (assuming a year has 365 days). Here are the conversions: Catherine (subjectID: f9057kp) - 414 days ÷ 365 = approximately 1.13 years Maddy (subjectID: f6188io) - 348 days ÷ 365 = approximately 0.95 years Jane (subjectID: f5001ob) - 478 days ÷ 365 = approximately 1.31 years Catherine (subjectID: f2709ul) - 462 days ÷ 365 = approximately 1.27 years Spot (subjectID: f4138ge) - 334 days ÷ 365 = approximately 0.92 years Sally (subjectID: f6318if) - 355 days ÷ 365 = approximately 0.97 years So, the ages of the silly subjects in years are approximately: 1.13, 0.95, 1.31, 1.27, 0.92, and 0.97 years.

chat 2

On 10 March I replaced the subjectID column with the ID one (as in the csv above), saved it in excel, and uploaded the xlsx to box as version 2 of the same file. Here is a copy of the Box AI chat I had with that updated file: (my prompts in bold)

what unit is the age column given in? 

The age column in the document is given in days.

how old are the silly subjects in years? 

To convert the ages from days to years, we divide each age by 365 (assuming a year has approximately 365 days). Here are the ages of the subjects associated with the color white in years: 1. Jane (ID: s109f) - 478 days ÷ 365 ≈ 1.31 years 2. Catherine (ID: s899q) - 414 days ÷ 365 ≈ 1.13 years 3. Maddy (ID: s945t) - 348 days ÷ 365 ≈ 0.95 years 4. Spot (ID: s165k) - 334 days ÷ 365 ≈ 0.92 years 5.
