fhe is a Python library typically used in Security, Encryption applications. fhe has no bugs, it has no vulnerabilities and it has low support. However fhe build file is not available. You can download it from GitHub.

An encryption scheme is fully homomorphic when it is possible to perform implicit addition and multiplication of plaintexts while manipulating only ciphertexts. The first construction of a fully homomorphic encryption (FHE) scheme was described by Gentry in 2009.

            Skip row if a specific cell is display value blank when running BulkPDFs Google Sheets
            Asked 2021-Oct-19 at 08:45

            I have a Google sheets with 65 lines set up for data. In every row some of the cells use dropdown list and others use an if formulas based on the selections of the dropdown choices. The final cell (CQ), through the use of an if statement in the cell, populates as follows;

            A) Returns "" if all other calculated cells in the row are blank B) Returns "DATA INCOMPLETE" if all the other calculated cells in the row do not meet specific criteria C) Returns "COMPLETED" if all calculated cells meet the specific criteria.

            My sheet currently has data in 10 lines however it is trying to generate 65 PDF files. In functionNMPRBulkPDF it is suppose to stop when it reaches a blank row however that is not happening. I believe this is occurring because it thinks a row is not blank because either:

            A) it sees the dropdown box as having data or B) it thinks the if formula is actual data even if the return is blank ("")

            I am not sure which.

            What I would like to be able to do is to use last cell in the row (CQ) to determine if the row should have a PDF file created for it. If the entry is "" or "COMPLETED" I would like to skip the row and go on to the next one. Or in other words only print the ones with "DATA INCOMPLETE" in that last cell (CQ)

            I have this working well other than this issue so any help will be highly appreciated. Please have patience with me as this is my first foray into Google Script and I am totally self taught.

            I believe your goal is as follows.

            • You want to check the column "CQ". When the value of column "CQ" is DATA INCOMPLETE, you want to skip in the loop of data.forEach(row => {,,,}).

            In this case, how about the following modification? I think that in your situation, there are several methods.

            powershell script to merge .csv files by filename prefix
            Asked 2021-Jan-19 at 12:43

            I'm currently trying to compare and merge .csv files that are named "xxx_yyy_zzz" by their respective filenames in Powershell. All files having the same "xxx_yyy" patterns are supposed to be merged into a single .csv file that is named "xxx_yyy", preferably into the same directory.

            I'm using for-loops and and ArrayList right now (I tried grouping the objects to use -Split or -SkipLast but had trouble with already existing merged files being read again). I got the comparison down (mostly), but I can't seem to merge the .csv files with the Import/Export commands.

            The files are being created and their names are correct, but they are always empty. I'm not sure I fully understand the correct usage oft Export-CSV and how to get multiple files into the command... Any help?

            I have used the raw data (get-content | selct-object -skip 2) instead of import csv. Then we use a foreach loop and an array to append the other file to then we export this full array using set-content to over write the file. Its a hacky fix but it worked for me in less time than and lines then any other script i tried to build for it.

            How are embeddings used for fully homomorphic encryption?
            Asked 2020-Jul-09 at 18:33

            How exactly do you perform one way encryption using embeddings from a deep neural network?

            Fully homomorphic encryption (FHE) benefits society by ensuring full privacy. The Private Identity recognition algorithm uses FHE to enable encrypted match and search operations on an encrypted dataset without any requirement to store, transmit or use plaintext biometrics or biometric templates. The biometric data is irreversibly anonymized using a 1-way cryptographic hash algorithm and then discarded without the data ever leaving the local device.

            My question is how exactly does this use embeddings to accomplish this? Where do embeddings come in?

            ...

            ANSWER

            Answered 2020-Jul-09 at 18:33

            An embedding is a set of floating point numbers taken from the N-1 layer of a softmax Deep Neural Network (DNN). Initially, the community used DNNs to get a resulting class (softmax), but an interesting property turned out to be the values at the layer before the softamx layer.

            These values have interesting properties. They may function as a 1-way encryption. They also closely relate to the initial input. In a geometric distance (cosine, Euclidean) values are close to similar inputs. This means two pictures of my face will be closer (geometrically) than a picture of two different people This property allows operations on the resulting encryption.

            One of the operations allowed is match. In the encrypted space, using the distance properties, we can match using only the embedding. Since we are only working in the encrypted space, we have an implementation of FHE and the embedding comes from the DNN.

            Subsequently, we have found that a second DNN allows the classification, but only using embeddings. We now have privacy and performance.

            Calculating the difference of entry values in pd.DataFrame comparing multiple indices
            Asked 2020-Jul-07 at 14:26

            I'd like to insert the difference of every two differences of the energy values out of a pd.DataFrame containing data of multiple bases (A, C, G, T, U1 and U2) for every base in every environment and so on. I thought of something like fhe following. I thought of iterating through the whole data frame, but it didn't work and is also definitely not how pd.DataFrames are intended to be used.
            E. g., I'd like having the difference in charge of base A in pbs between its "neutral" and its "positive" value expanding the princple for every base, environment and maybe more criteria, which could be added in future.

            Although I heard of pandas.MultiIndex, I didn't have much experience with it, but this looks like a possible solution to me, isn't it?

            Only the first subtraction is reflected in the code, as it was unclear how many calculations there were. I think it's easy to follow this format.

            Process flow:

            1. data frame transformation
            2. Eliminate multiple indexes.
            3. change the column name
