Arcjet 脱敏

Arcjet 脱敏集成允许您在将提示发送给 LLM 之前，从中脱敏敏感的用户信息。

Arcjet 脱敏完全在您自己的机器上运行，从不将数据发送到其他任何地方，确保了最佳的隐私和性能。

Arcjet 脱敏对象本身不是一个 LLM，而是封装了一个 LLM。它会脱敏输入的文本，然后在返回之前对封装的 LLM 的输出进行反脱敏。

安装​

安装 Arcjet 脱敏库：

:::提示 请参阅安装集成包的一般说明部分。 :::

yarn add @arcjet/redact

并安装 LangChain Community：

:::提示 请参阅安装集成包的一般说明部分。 :::

yarn add @langchain/community @langchain/core

现在，您就可以开始使用Arcjet脱敏保护您的LLM调用了！

用法​

import {
  ArcjetRedact,
  ArcjetSensitiveInfoType,
} from "@langchain/community/llms/arcjet";
import { OpenAI } from "@langchain/openai";

// Create an instance of another LLM for Arcjet to wrap
const openai = new OpenAI({
  modelName: "gpt-3.5-turbo-instruct",
  openAIApiKey: process.env.OPENAI_API_KEY,
});

const arcjetRedactOptions = {
  // Specify a LLM that Arcjet Redact will call once it has redacted the input.
  llm: openai,

  // Specify the list of entities that should be redacted.
  // If this isn't specified then all entities will be redacted.
  entities: [
    "email",
    "phone-number",
    "ip-address",
    "credit-card",
  ] as ArcjetSensitiveInfoType[],

  // You can provide a custom detect function to detect entities that we don't support yet.
  // It takes a list of tokens and you return a list of identified types or undefined.
  // The undefined types that you return should be added to the entities list if used.
  detect: (tokens: string[]) => {
    return tokens.map((t) =>
      t === "some-sensitive-info" ? "custom-entity" : undefined
    );
  },

  // The number of tokens to provide to the custom detect function. This defaults to 1.
  // It can be used to provide additional context when detecting custom entity types.
  contextWindowSize: 1,

  // This allows you to provide custom replacements when redacting. Please ensure
  // that the replacements are unique so that unredaction works as expected.
  replace: (identifiedType: string) => {
    return identifiedType === "email" ? "[email protected]" : undefined;
  },
};

const arcjetRedact = new ArcjetRedact(arcjetRedactOptions);
const response = await arcjetRedact.invoke(
  "My email address is [email protected], here is some-sensitive-info"
);
